Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147478692, here are decompositions:

  • 19 + 2147478673 = 2147478692
  • 31 + 2147478661 = 2147478692
  • 43 + 2147478649 = 2147478692
  • 211 + 2147478481 = 2147478692
  • 433 + 2147478259 = 2147478692
  • 439 + 2147478253 = 2147478692
  • 613 + 2147478079 = 2147478692
  • 643 + 2147478049 = 2147478692

Showing the first eight; more decompositions exist.
