Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609708, here are decompositions:

  • 5 + 31609703 = 31609708
  • 17 + 31609691 = 31609708
  • 29 + 31609679 = 31609708
  • 47 + 31609661 = 31609708
  • 131 + 31609577 = 31609708
  • 167 + 31609541 = 31609708
  • 227 + 31609481 = 31609708
  • 239 + 31609469 = 31609708

Showing the first eight; more decompositions exist.
