Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 995978, here are decompositions:

  • 19 + 995959 = 995978
  • 37 + 995941 = 995978
  • 97 + 995881 = 995978
  • 241 + 995737 = 995978
  • 337 + 995641 = 995978
  • 367 + 995611 = 995978
  • 439 + 995539 = 995978
  • 547 + 995431 = 995978

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 995,978 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 995978 first appears in π at position 319,754 of the decimal expansion (the 319,754ordinal-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.
