Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149418, here are decompositions:

  • 7 + 149411 = 149418
  • 19 + 149399 = 149418
  • 37 + 149381 = 149418
  • 41 + 149377 = 149418
  • 47 + 149371 = 149418
  • 67 + 149351 = 149418
  • 109 + 149309 = 149418
  • 131 + 149287 = 149418

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 149,418 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 149418 first appears in π at position 113,492 of the decimal expansion (the 113,492ordinal-suffix:nd 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.
