Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147450402, here are decompositions:

  • 79 + 2147450323 = 2147450402
  • 109 + 2147450293 = 2147450402
  • 193 + 2147450209 = 2147450402
  • 613 + 2147449789 = 2147450402
  • 619 + 2147449783 = 2147450402
  • 1093 + 2147449309 = 2147450402
  • 1123 + 2147449279 = 2147450402
  • 1249 + 2147449153 = 2147450402

Showing the first eight; more decompositions exist.
