Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 66430, here are decompositions:

  • 17 + 66413 = 66430
  • 47 + 66383 = 66430
  • 53 + 66377 = 66430
  • 71 + 66359 = 66430
  • 83 + 66347 = 66430
  • 137 + 66293 = 66430
  • 191 + 66239 = 66430
  • 239 + 66191 = 66430

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 66430 first appears in π at position 516 of the decimal expansion (the 516ordinal-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.
