Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23580, here are decompositions:

  • 13 + 23567 = 23580
  • 17 + 23563 = 23580
  • 19 + 23561 = 23580
  • 23 + 23557 = 23580
  • 31 + 23549 = 23580
  • 41 + 23539 = 23580
  • 43 + 23537 = 23580
  • 71 + 23509 = 23580

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23580 first appears in π at position 4,318 of the decimal expansion (the 4,318ordinal-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.
