Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6850, here are decompositions:

  • 17 + 6833 = 6850
  • 23 + 6827 = 6850
  • 47 + 6803 = 6850
  • 59 + 6791 = 6850
  • 71 + 6779 = 6850
  • 89 + 6761 = 6850
  • 113 + 6737 = 6850
  • 131 + 6719 = 6850

Showing the first eight; more decompositions exist.

Musical pitch

Heard as a frequency, 6,850 Hz is closest to:

  • Concert pitch (A4 = 440 Hz): A8 (7040 Hz, -47¢ — about midway to G♯8)
  • Scientific pitch (C4 = 256 Hz): A8 (6888.6 Hz, -10¢)
  • Baroque pitch (A4 = 415 Hz): A♯8 (7034.8 Hz, -46¢ — about midway to A8)
Position in π

The digit sequence 6850 first appears in π at position 835 of the decimal expansion (the 835ordinal-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.
