Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497294, here are decompositions:

  • 251 + 2147497043 = 2147497294
  • 353 + 2147496941 = 2147497294
  • 431 + 2147496863 = 2147497294
  • 563 + 2147496731 = 2147497294
  • 587 + 2147496707 = 2147497294
  • 641 + 2147496653 = 2147497294
  • 743 + 2147496551 = 2147497294
  • 857 + 2147496437 = 2147497294

Showing the first eight; more decompositions exist.
