Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497922, here are decompositions:

  • 151 + 2147497771 = 2147497922
  • 223 + 2147497699 = 2147497922
  • 433 + 2147497489 = 2147497922
  • 463 + 2147497459 = 2147497922
  • 601 + 2147497321 = 2147497922
  • 883 + 2147497039 = 2147497922
  • 1063 + 2147496859 = 2147497922
  • 1069 + 2147496853 = 2147497922

Showing the first eight; more decompositions exist.
