Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154892, here are decompositions:

  • 19 + 154873 = 154892
  • 43 + 154849 = 154892
  • 103 + 154789 = 154892
  • 139 + 154753 = 154892
  • 193 + 154699 = 154892
  • 211 + 154681 = 154892
  • 223 + 154669 = 154892
  • 271 + 154621 = 154892

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 154,892 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 154892 first appears in π at position 344,116 of the decimal expansion (the 344,116ordinal-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.
