Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147470802, here are decompositions:

  • 13 + 2147470789 = 2147470802
  • 31 + 2147470771 = 2147470802
  • 79 + 2147470723 = 2147470802
  • 199 + 2147470603 = 2147470802
  • 223 + 2147470579 = 2147470802
  • 271 + 2147470531 = 2147470802
  • 349 + 2147470453 = 2147470802
  • 619 + 2147470183 = 2147470802

Showing the first eight; more decompositions exist.
