Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16002, here are decompositions:

  • 11 + 15991 = 16002
  • 29 + 15973 = 16002
  • 31 + 15971 = 16002
  • 43 + 15959 = 16002
  • 79 + 15923 = 16002
  • 83 + 15919 = 16002
  • 89 + 15913 = 16002
  • 101 + 15901 = 16002

Showing the first eight; more decompositions exist.

  • Concert pitch (A4 = 440 Hz): B9 (15804.3 Hz, +22¢)
  • Scientific pitch (C4 = 256 Hz): C10 (16384 Hz, -41¢)
  • Baroque pitch (A4 = 415 Hz): C10 (15792.7 Hz, +23¢)
Position in π

The digit sequence 16002 first appears in π at position 26,424 of the decimal expansion (the 26,424ordinal-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.
