Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497802, here are decompositions:

  • 31 + 2147497771 = 2147497802
  • 103 + 2147497699 = 2147497802
  • 139 + 2147497663 = 2147497802
  • 313 + 2147497489 = 2147497802
  • 409 + 2147497393 = 2147497802
  • 601 + 2147497201 = 2147497802
  • 661 + 2147497141 = 2147497802
  • 823 + 2147496979 = 2147497802

Showing the first eight; more decompositions exist.
