Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978678, here are decompositions:

  • 31 + 978647 = 978678
  • 59 + 978619 = 978678
  • 61 + 978617 = 978678
  • 67 + 978611 = 978678
  • 79 + 978599 = 978678
  • 109 + 978569 = 978678
  • 137 + 978541 = 978678
  • 157 + 978521 = 978678

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 978,678 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 978678 first appears in π at position 843,233 of the decimal expansion (the 843,233ordinal-suffix:rd 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.
