Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989200, here are decompositions:

  • 29 + 989171 = 989200
  • 101 + 989099 = 989200
  • 263 + 988937 = 989200
  • 467 + 988733 = 989200
  • 557 + 988643 = 989200
  • 593 + 988607 = 989200
  • 617 + 988583 = 989200
  • 659 + 988541 = 989200

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 989,200 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 989200 first appears in π at position 950,240 of the decimal expansion (the 950,240ordinal-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.
