Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544750, here are decompositions:

  • 31 + 31544719 = 31544750
  • 37 + 31544713 = 31544750
  • 163 + 31544587 = 31544750
  • 199 + 31544551 = 31544750
  • 241 + 31544509 = 31544750
  • 379 + 31544371 = 31544750
  • 439 + 31544311 = 31544750
  • 571 + 31544179 = 31544750

Showing the first eight; more decompositions exist.
