Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978722, here are decompositions:

  • 79 + 978643 = 978722
  • 103 + 978619 = 978722
  • 181 + 978541 = 978722
  • 211 + 978511 = 978722
  • 373 + 978349 = 978722
  • 379 + 978343 = 978722
  • 439 + 978283 = 978722
  • 499 + 978223 = 978722

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 978,722 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 978722 first appears in π at position 705,499 of the decimal expansion (the 705,499ordinal-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.
