Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491660, here are decompositions:

  • 53 + 2147491607 = 2147491660
  • 101 + 2147491559 = 2147491660
  • 107 + 2147491553 = 2147491660
  • 113 + 2147491547 = 2147491660
  • 257 + 2147491403 = 2147491660
  • 311 + 2147491349 = 2147491660
  • 317 + 2147491343 = 2147491660
  • 383 + 2147491277 = 2147491660

Showing the first eight; more decompositions exist.
