Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 23988, here are decompositions:

  • 7 + 23981 = 23988
  • 11 + 23977 = 23988
  • 17 + 23971 = 23988
  • 31 + 23957 = 23988
  • 59 + 23929 = 23988
  • 71 + 23917 = 23988
  • 79 + 23909 = 23988
  • 89 + 23899 = 23988

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 23988 first appears in π at position 23,217 of the decimal expansion (the 23,217ordinal-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.
