Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4560, here are decompositions:

  • 11 + 4549 = 4560
  • 13 + 4547 = 4560
  • 37 + 4523 = 4560
  • 41 + 4519 = 4560
  • 43 + 4517 = 4560
  • 47 + 4513 = 4560
  • 53 + 4507 = 4560
  • 67 + 4493 = 4560

Showing the first eight; more decompositions exist.

  • Concert pitch (A4 = 440 Hz): C♯8 (4434.9 Hz, +48¢ — about midway to D8)
  • Scientific pitch (C4 = 256 Hz): D8 (4597.6 Hz, -14¢)
  • Baroque pitch (A4 = 415 Hz): D8 (4431.7 Hz, +49¢ — about midway to D♯8)
Position in π

The digit sequence 4560 first appears in π at position 1,874 of the decimal expansion (the 1,874ordinal-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.
