Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 3718, here are decompositions:

  • 17 + 3701 = 3718
  • 41 + 3677 = 3718
  • 47 + 3671 = 3718
  • 59 + 3659 = 3718
  • 101 + 3617 = 3718
  • 137 + 3581 = 3718
  • 179 + 3539 = 3718
  • 191 + 3527 = 3718

Showing the first eight; more decompositions exist.

BILE

A staple of calculator humor since pocket calculators put digits in front of bored students.

Musical pitch

Heard as a frequency, 3,718 Hz is closest to:

  • Concert pitch (A4 = 440 Hz): A♯7 (3729.3 Hz, -5¢)
  • Scientific pitch (C4 = 256 Hz): A♯7 (3649.1 Hz, +32¢)
  • Baroque pitch (A4 = 415 Hz): B7 (3726.6 Hz, -4¢)
Position in π

The digit sequence 3718 first appears in π at position 2,774 of the decimal expansion (the 2,774ordinal-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.
