Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182784, here are decompositions:

  • 5 + 182779 = 182784
  • 11 + 182773 = 182784
  • 37 + 182747 = 182784
  • 71 + 182713 = 182784
  • 73 + 182711 = 182784
  • 83 + 182701 = 182784
  • 97 + 182687 = 182784
  • 103 + 182681 = 182784

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 182,784 and was likely granted around 1875.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 182784 first appears in π at position 250,273 of the decimal expansion (the 250,273ordinal-suffix:rd 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.
