Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15260, here are decompositions:

  • 19 + 15241 = 15260
  • 43 + 15217 = 15260
  • 61 + 15199 = 15260
  • 67 + 15193 = 15260
  • 73 + 15187 = 15260
  • 139 + 15121 = 15260
  • 199 + 15061 = 15260
  • 229 + 15031 = 15260

Showing the first eight; more decompositions exist.

  • Concert pitch (A4 = 440 Hz): A♯9 (14917.2 Hz, +39¢)
  • Scientific pitch (C4 = 256 Hz): B9 (15464.4 Hz, -23¢)
  • Baroque pitch (A4 = 415 Hz): B9 (14906.3 Hz, +41¢)
Position in π

The digit sequence 15260 first appears in π at position 34,545 of the decimal expansion (the 34,545ordinal-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.
