Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 145948, here are decompositions:

  • 17 + 145931 = 145948
  • 149 + 145799 = 145948
  • 191 + 145757 = 145948
  • 227 + 145721 = 145948
  • 239 + 145709 = 145948
  • 269 + 145679 = 145948
  • 311 + 145637 = 145948
  • 347 + 145601 = 145948

Showing the first eight; more decompositions exist.

Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 145,948 and was likely granted around 1873.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 145948 first appears in π at position 360,349 of the decimal expansion (the 360,349ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
