Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109806, here are decompositions:

  • 13 + 109793 = 109806
  • 17 + 109789 = 109806
  • 89 + 109717 = 109806
  • 167 + 109639 = 109806
  • 197 + 109609 = 109806
  • 223 + 109583 = 109806
  • 227 + 109579 = 109806
  • 239 + 109567 = 109806

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 109,806 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 109806 first appears in π at position 543,679 of the decimal expansion (the 543,679ordinal-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.
