Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147469942, here are decompositions:

  • 61 + 2147469881 = 2147469942
  • 113 + 2147469829 = 2147469942
  • 239 + 2147469703 = 2147469942
  • 263 + 2147469679 = 2147469942
  • 283 + 2147469659 = 2147469942
  • 313 + 2147469629 = 2147469942
  • 349 + 2147469593 = 2147469942
  • 389 + 2147469553 = 2147469942

Showing the first eight; more decompositions exist.
