Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154916, here are decompositions:

  • 19 + 154897 = 154916
  • 43 + 154873 = 154916
  • 67 + 154849 = 154916
  • 109 + 154807 = 154916
  • 127 + 154789 = 154916
  • 163 + 154753 = 154916
  • 193 + 154723 = 154916
  • 337 + 154579 = 154916

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 154,916 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 154916 first appears in π at position 698,754 of the decimal expansion (the 698,754ordinal-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.
