Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497442, here are decompositions:

  • 31 + 2147497411 = 2147497442
  • 199 + 2147497243 = 2147497442
  • 241 + 2147497201 = 2147497442
  • 463 + 2147496979 = 2147497442
  • 613 + 2147496829 = 2147497442
  • 691 + 2147496751 = 2147497442
  • 709 + 2147496733 = 2147497442
  • 1093 + 2147496349 = 2147497442

Showing the first eight; more decompositions exist.
