Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16238, here are decompositions:

  • 7 + 16231 = 16238
  • 97 + 16141 = 16238
  • 127 + 16111 = 16238
  • 151 + 16087 = 16238
  • 181 + 16057 = 16238
  • 331 + 15907 = 16238
  • 337 + 15901 = 16238
  • 349 + 15889 = 16238

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16238 first appears in π at position 53,417 of the decimal expansion (the 53,417ordinal-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.
