Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147530388, here are decompositions:

  • 127 + 2147530261 = 2147530388
  • 277 + 2147530111 = 2147530388
  • 379 + 2147530009 = 2147530388
  • 739 + 2147529649 = 2147530388
  • 937 + 2147529451 = 2147530388
  • 1009 + 2147529379 = 2147530388
  • 1237 + 2147529151 = 2147530388
  • 1399 + 2147528989 = 2147530388

Showing the first eight; more decompositions exist.
