Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989800, here are decompositions:

  • 3 + 989797 = 989800
  • 17 + 989783 = 989800
  • 23 + 989777 = 989800
  • 47 + 989753 = 989800
  • 113 + 989687 = 989800
  • 137 + 989663 = 989800
  • 239 + 989561 = 989800
  • 293 + 989507 = 989800

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 989,800 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 989800 first appears in π at position 139,251 of the decimal expansion (the 139,251ordinal-suffix:st 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.
