Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 85370, here are decompositions:

  • 7 + 85363 = 85370
  • 37 + 85333 = 85370
  • 67 + 85303 = 85370
  • 73 + 85297 = 85370
  • 127 + 85243 = 85370
  • 157 + 85213 = 85370
  • 211 + 85159 = 85370
  • 223 + 85147 = 85370

Showing the first eight; more decompositions exist.

Position in π

The digit sequence 85370 first appears in π at position 80,063 of the decimal expansion (the 80,063ordinal-suffix:rd 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.
