Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144148, here are decompositions:

  • 149 + 143999 = 144148
  • 167 + 143981 = 144148
  • 239 + 143909 = 144148
  • 269 + 143879 = 144148
  • 317 + 143831 = 144148
  • 419 + 143729 = 144148
  • 449 + 143699 = 144148
  • 461 + 143687 = 144148

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 144,148 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 144148 first appears in π at position 72,877 of the decimal expansion (the 72,877ordinal-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.
