Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 106820, here are decompositions:

  • 19 + 106801 = 106820
  • 37 + 106783 = 106820
  • 61 + 106759 = 106820
  • 67 + 106753 = 106820
  • 73 + 106747 = 106820
  • 127 + 106693 = 106820
  • 139 + 106681 = 106820
  • 151 + 106669 = 106820

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 106,820 and was likely granted around 1870.

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

Position in π

The digit sequence 106820 first appears in π at position 29,558 of the decimal expansion (the 29,558ordinal-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.
