Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19284, here are decompositions:

  • 11 + 19273 = 19284
  • 17 + 19267 = 19284
  • 47 + 19237 = 19284
  • 53 + 19231 = 19284
  • 71 + 19213 = 19284
  • 73 + 19211 = 19284
  • 101 + 19183 = 19284
  • 103 + 19181 = 19284

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19284 first appears in π at position 47,181 of the decimal expansion (the 47,181ordinal-suffix:st 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.
