Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491844, here are decompositions:

  • 7 + 2147491837 = 2147491844
  • 13 + 2147491831 = 2147491844
  • 241 + 2147491603 = 2147491844
  • 271 + 2147491573 = 2147491844
  • 307 + 2147491537 = 2147491844
  • 367 + 2147491477 = 2147491844
  • 571 + 2147491273 = 2147491844
  • 607 + 2147491237 = 2147491844

Showing the first eight; more decompositions exist.
