Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147466528, here are decompositions:

  • 7 + 2147466521 = 2147466528
  • 41 + 2147466487 = 2147466528
  • 71 + 2147466457 = 2147466528
  • 79 + 2147466449 = 2147466528
  • 89 + 2147466439 = 2147466528
  • 101 + 2147466427 = 2147466528
  • 191 + 2147466337 = 2147466528
  • 199 + 2147466329 = 2147466528

Showing the first eight; more decompositions exist.
