Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 978664, here are decompositions:

  • 17 + 978647 = 978664
  • 47 + 978617 = 978664
  • 53 + 978611 = 978664
  • 173 + 978491 = 978664
  • 191 + 978473 = 978664
  • 251 + 978413 = 978664
  • 317 + 978347 = 978664
  • 431 + 978233 = 978664

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 978,664 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 978664 first appears in π at position 483,563 of the decimal expansion (the 483,563ordinal-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.
