Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978806, here are decompositions:

  • 7 + 978799 = 978806
  • 79 + 978727 = 978806
  • 109 + 978697 = 978806
  • 163 + 978643 = 978806
  • 349 + 978457 = 978806
  • 379 + 978427 = 978806
  • 457 + 978349 = 978806
  • 463 + 978343 = 978806

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 978,806 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 978806 first appears in π at position 357,235 of the decimal expansion (the 357,235ordinal-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.
