Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468642, here are decompositions:

  • 3 + 2147468639 = 2147468642
  • 43 + 2147468599 = 2147468642
  • 79 + 2147468563 = 2147468642
  • 139 + 2147468503 = 2147468642
  • 199 + 2147468443 = 2147468642
  • 211 + 2147468431 = 2147468642
  • 373 + 2147468269 = 2147468642
  • 409 + 2147468233 = 2147468642

Showing the first eight; more decompositions exist.
