Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544536, here are decompositions:

  • 3 + 31544533 = 31544536
  • 5 + 31544531 = 31544536
  • 173 + 31544363 = 31544536
  • 239 + 31544297 = 31544536
  • 347 + 31544189 = 31544536
  • 383 + 31544153 = 31544536
  • 479 + 31544057 = 31544536
  • 503 + 31544033 = 31544536

Showing the first eight; more decompositions exist.
