Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149786, here are decompositions:

  • 19 + 149767 = 149786
  • 37 + 149749 = 149786
  • 73 + 149713 = 149786
  • 97 + 149689 = 149786
  • 157 + 149629 = 149786
  • 163 + 149623 = 149786
  • 223 + 149563 = 149786
  • 283 + 149503 = 149786

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 149,786 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 149786 first appears in π at position 711,191 of the decimal expansion (the 711,191ordinal-suffix:st 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.
