Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989830, here are decompositions:

  • 3 + 989827 = 989830
  • 47 + 989783 = 989830
  • 53 + 989777 = 989830
  • 167 + 989663 = 989830
  • 251 + 989579 = 989830
  • 269 + 989561 = 989830
  • 353 + 989477 = 989830
  • 389 + 989441 = 989830

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 989,830 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 989830 first appears in π at position 599,618 of the decimal expansion (the 599,618ordinal-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.
