Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 37818, here are decompositions:

  • 5 + 37813 = 37818
  • 7 + 37811 = 37818
  • 19 + 37799 = 37818
  • 37 + 37781 = 37818
  • 71 + 37747 = 37818
  • 101 + 37717 = 37818
  • 127 + 37691 = 37818
  • 199 + 37619 = 37818

Showing the first eight; more decompositions exist.

A staple of calculator humor since pocket calculators put digits in front of bored students.

Position in π

The digit sequence 37818 first appears in π at position 174,408 of the decimal expansion (the 174,408ordinal-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.
