Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20732, here are decompositions:

  • 13 + 20719 = 20732
  • 139 + 20593 = 20732
  • 181 + 20551 = 20732
  • 199 + 20533 = 20732
  • 211 + 20521 = 20732
  • 223 + 20509 = 20732
  • 373 + 20359 = 20732
  • 379 + 20353 = 20732

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20732 first appears in π at position 338,558 of the decimal expansion (the 338,558ordinal-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.
