Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491798, here are decompositions:

  • 17 + 2147491781 = 2147491798
  • 41 + 2147491757 = 2147491798
  • 107 + 2147491691 = 2147491798
  • 191 + 2147491607 = 2147491798
  • 239 + 2147491559 = 2147491798
  • 251 + 2147491547 = 2147491798
  • 281 + 2147491517 = 2147491798
  • 449 + 2147491349 = 2147491798

Showing the first eight; more decompositions exist.
