Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16604, here are decompositions:

  • 31 + 16573 = 16604
  • 37 + 16567 = 16604
  • 43 + 16561 = 16604
  • 127 + 16477 = 16604
  • 151 + 16453 = 16604
  • 157 + 16447 = 16604
  • 193 + 16411 = 16604
  • 223 + 16381 = 16604

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16604 first appears in π at position 70,872 of the decimal expansion (the 70,872ordinal-suffix:nd 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.
