Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158940, here are decompositions:

  • 13 + 158927 = 158940
  • 17 + 158923 = 158940
  • 31 + 158909 = 158940
  • 59 + 158881 = 158940
  • 73 + 158867 = 158940
  • 97 + 158843 = 158940
  • 137 + 158803 = 158940
  • 149 + 158791 = 158940

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 158,940 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 158940 first appears in π at position 578,139 of the decimal expansion (the 578,139ordinal-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.
