Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156930, here are decompositions:

  • 17 + 156913 = 156930
  • 29 + 156901 = 156930
  • 31 + 156899 = 156930
  • 43 + 156887 = 156930
  • 89 + 156841 = 156930
  • 97 + 156833 = 156930
  • 107 + 156823 = 156930
  • 113 + 156817 = 156930

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 156,930 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 156930 first appears in π at position 113,221 of the decimal expansion (the 113,221ordinal-suffix:st 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.
