Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109784, here are decompositions:

  • 43 + 109741 = 109784
  • 67 + 109717 = 109784
  • 163 + 109621 = 109784
  • 277 + 109507 = 109784
  • 313 + 109471 = 109784
  • 331 + 109453 = 109784
  • 397 + 109387 = 109784
  • 421 + 109363 = 109784

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 109,784 and was likely granted around 1871.

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

Position in π

The digit sequence 109784 first appears in π at position 243,170 of the decimal expansion (the 243,170ordinal-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.
