Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147453670, here are decompositions:

  • 13 + 2147453657 = 2147453670
  • 17 + 2147453653 = 2147453670
  • 23 + 2147453647 = 2147453670
  • 31 + 2147453639 = 2147453670
  • 71 + 2147453599 = 2147453670
  • 107 + 2147453563 = 2147453670
  • 113 + 2147453557 = 2147453670
  • 139 + 2147453531 = 2147453670

Showing the first eight; more decompositions exist.
