Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8630, here are decompositions:

  • 3 + 8627 = 8630
  • 7 + 8623 = 8630
  • 31 + 8599 = 8630
  • 67 + 8563 = 8630
  • 103 + 8527 = 8630
  • 109 + 8521 = 8630
  • 163 + 8467 = 8630
  • 199 + 8431 = 8630

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 8630 first appears in π at position 1,898 of the decimal expansion (the 1,898ordinal-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.
