Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147375170, here are decompositions:

  • 29 + 2147375141 = 2147375170
  • 71 + 2147375099 = 2147375170
  • 173 + 2147374997 = 2147375170
  • 383 + 2147374787 = 2147375170
  • 443 + 2147374727 = 2147375170
  • 593 + 2147374577 = 2147375170
  • 839 + 2147374331 = 2147375170
  • 887 + 2147374283 = 2147375170

Showing the first eight; more decompositions exist.
