Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149866, here are decompositions:

  • 5 + 149861 = 149866
  • 29 + 149837 = 149866
  • 107 + 149759 = 149866
  • 137 + 149729 = 149866
  • 149 + 149717 = 149866
  • 239 + 149627 = 149866
  • 263 + 149603 = 149866
  • 347 + 149519 = 149866

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 149,866 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 149866 first appears in π at position 506,516 of the decimal expansion (the 506,516ordinal-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.
