Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600, here are decompositions:

  • 3 + 8597 = 8600
  • 19 + 8581 = 8600
  • 37 + 8563 = 8600
  • 61 + 8539 = 8600
  • 73 + 8527 = 8600
  • 79 + 8521 = 8600
  • 139 + 8461 = 8600
  • 157 + 8443 = 8600

Showing the first eight; more decompositions exist.

  • Concert pitch (A4 = 440 Hz): C9 (8372 Hz, +47¢ — about midway to C♯9)
  • Scientific pitch (C4 = 256 Hz): C♯9 (8679.1 Hz, -16¢)
  • Baroque pitch (A4 = 415 Hz): C♯9 (8365.9 Hz, +48¢ — about midway to D9)
Position in π

The digit sequence 8600 first appears in π at position 7,919 of the decimal expansion (the 7,919ordinal-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.
