Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8230, here are decompositions:

  • 11 + 8219 = 8230
  • 59 + 8171 = 8230
  • 83 + 8147 = 8230
  • 107 + 8123 = 8230
  • 113 + 8117 = 8230
  • 137 + 8093 = 8230
  • 149 + 8081 = 8230
  • 191 + 8039 = 8230

Showing the first eight; more decompositions exist.

  • Concert pitch (A4 = 440 Hz): C9 (8372 Hz, -30¢)
  • Scientific pitch (C4 = 256 Hz): C9 (8192 Hz, +8¢)
  • Baroque pitch (A4 = 415 Hz): C♯9 (8365.9 Hz, -28¢)
Position in π

The digit sequence 8230 first appears in π at position 113 of the decimal expansion (the 113ordinal-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.
