Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989540, here are decompositions:

  • 7 + 989533 = 989540
  • 61 + 989479 = 989540
  • 73 + 989467 = 989540
  • 163 + 989377 = 989540
  • 193 + 989347 = 989540
  • 199 + 989341 = 989540
  • 367 + 989173 = 989540
  • 421 + 989119 = 989540

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 989,540 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 989540 first appears in π at position 50,421 of the decimal expansion (the 50,421ordinal-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.
