Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545626, here are decompositions:

  • 3 + 31545623 = 31545626
  • 19 + 31545607 = 31545626
  • 127 + 31545499 = 31545626
  • 139 + 31545487 = 31545626
  • 157 + 31545469 = 31545626
  • 283 + 31545343 = 31545626
  • 577 + 31545049 = 31545626
  • 727 + 31544899 = 31545626

Showing the first eight; more decompositions exist.
