Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19358, here are decompositions:

  • 109 + 19249 = 19358
  • 127 + 19231 = 19358
  • 139 + 19219 = 19358
  • 151 + 19207 = 19358
  • 271 + 19087 = 19358
  • 277 + 19081 = 19358
  • 307 + 19051 = 19358
  • 349 + 19009 = 19358

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 19358 first appears in π at position 78,678 of the decimal expansion (the 78,678ordinal-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.
