Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993980, here are decompositions:

  • 3 + 993977 = 993980
  • 19 + 993961 = 993980
  • 37 + 993943 = 993980
  • 61 + 993919 = 993980
  • 67 + 993913 = 993980
  • 73 + 993907 = 993980
  • 139 + 993841 = 993980
  • 157 + 993823 = 993980

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 993,980 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 993980 first appears in π at position 594,242 of the decimal expansion (the 594,242ordinal-suffix:nd 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.
