Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157916, here are decompositions:

  • 19 + 157897 = 157916
  • 79 + 157837 = 157916
  • 103 + 157813 = 157916
  • 277 + 157639 = 157916
  • 337 + 157579 = 157916
  • 373 + 157543 = 157916
  • 397 + 157519 = 157916
  • 433 + 157483 = 157916

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 157,916 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 157916 first appears in π at position 430,856 of the decimal expansion (the 430,856ordinal-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.
