Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978804, here are decompositions:

  • 5 + 978799 = 978804
  • 7 + 978797 = 978804
  • 31 + 978773 = 978804
  • 61 + 978743 = 978804
  • 107 + 978697 = 978804
  • 157 + 978647 = 978804
  • 193 + 978611 = 978804
  • 263 + 978541 = 978804

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 978,804 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 978804 first appears in π at position 274,643 of the decimal expansion (the 274,643ordinal-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.
