Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16004, here are decompositions:

  • 3 + 16001 = 16004
  • 13 + 15991 = 16004
  • 31 + 15973 = 16004
  • 67 + 15937 = 16004
  • 97 + 15907 = 16004
  • 103 + 15901 = 16004
  • 127 + 15877 = 16004
  • 181 + 15823 = 16004

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16004 first appears in π at position 122,587 of the decimal expansion (the 122,587ordinal-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.
