Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474750, here are decompositions:

  • 3 + 31474747 = 31474750
  • 17 + 31474733 = 31474750
  • 29 + 31474721 = 31474750
  • 59 + 31474691 = 31474750
  • 149 + 31474601 = 31474750
  • 173 + 31474577 = 31474750
  • 179 + 31474571 = 31474750
  • 191 + 31474559 = 31474750

Showing the first eight; more decompositions exist.
