Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157888, here are decompositions:

  • 11 + 157877 = 157888
  • 47 + 157841 = 157888
  • 89 + 157799 = 157888
  • 149 + 157739 = 157888
  • 167 + 157721 = 157888
  • 239 + 157649 = 157888
  • 251 + 157637 = 157888
  • 317 + 157571 = 157888

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 157,888 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 157888 first appears in π at position 651,335 of the decimal expansion (the 651,335ordinal-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.
