Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15392, here are decompositions:

  • 19 + 15373 = 15392
  • 31 + 15361 = 15392
  • 43 + 15349 = 15392
  • 61 + 15331 = 15392
  • 73 + 15319 = 15392
  • 79 + 15313 = 15392
  • 103 + 15289 = 15392
  • 151 + 15241 = 15392

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 15392 first appears in π at position 196,316 of the decimal expansion (the 196,316ordinal-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.
