Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 16424, here are decompositions:

  • 3 + 16421 = 16424
  • 7 + 16417 = 16424
  • 13 + 16411 = 16424
  • 43 + 16381 = 16424
  • 61 + 16363 = 16424
  • 151 + 16273 = 16424
  • 157 + 16267 = 16424
  • 193 + 16231 = 16424

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 16424 first appears in π at position 83,311 of the decimal expansion (the 83,311ordinal-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.
