Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154908, here are decompositions:

  • 11 + 154897 = 154908
  • 31 + 154877 = 154908
  • 37 + 154871 = 154908
  • 59 + 154849 = 154908
  • 67 + 154841 = 154908
  • 101 + 154807 = 154908
  • 109 + 154799 = 154908
  • 139 + 154769 = 154908

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 154,908 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 154908 first appears in π at position 135,719 of the decimal expansion (the 135,719ordinal-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.
