Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978872, here are decompositions:

  • 19 + 978853 = 978872
  • 73 + 978799 = 978872
  • 229 + 978643 = 978872
  • 331 + 978541 = 978872
  • 409 + 978463 = 978872
  • 523 + 978349 = 978872
  • 691 + 978181 = 978872
  • 823 + 978049 = 978872

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 978,872 and was likely granted around 1910.

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

Position in π

The digit sequence 978872 first appears in π at position 695,368 of the decimal expansion (the 695,368ordinal-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.
