Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497228, here are decompositions:

  • 257 + 2147496971 = 2147497228
  • 311 + 2147496917 = 2147497228
  • 389 + 2147496839 = 2147497228
  • 449 + 2147496779 = 2147497228
  • 521 + 2147496707 = 2147497228
  • 599 + 2147496629 = 2147497228
  • 659 + 2147496569 = 2147497228
  • 677 + 2147496551 = 2147497228

Showing the first eight; more decompositions exist.
