Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20476, here are decompositions:

  • 83 + 20393 = 20476
  • 107 + 20369 = 20476
  • 149 + 20327 = 20476
  • 179 + 20297 = 20476
  • 227 + 20249 = 20476
  • 257 + 20219 = 20476
  • 293 + 20183 = 20476
  • 347 + 20129 = 20476

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 20476 first appears in π at position 186,729 of the decimal expansion (the 186,729ordinal-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.
