Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574702, here are decompositions:

  • 13 + 31574689 = 31574702
  • 31 + 31574671 = 31574702
  • 139 + 31574563 = 31574702
  • 223 + 31574479 = 31574702
  • 283 + 31574419 = 31574702
  • 373 + 31574329 = 31574702
  • 499 + 31574203 = 31574702
  • 571 + 31574131 = 31574702

Showing the first eight; more decompositions exist.
