Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156938, here are decompositions:

  • 37 + 156901 = 156938
  • 97 + 156841 = 156938
  • 139 + 156799 = 156938
  • 157 + 156781 = 156938
  • 211 + 156727 = 156938
  • 307 + 156631 = 156938
  • 337 + 156601 = 156938
  • 349 + 156589 = 156938

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 156,938 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 156938 first appears in π at position 262,367 of the decimal expansion (the 262,367ordinal-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.
