Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491860, here are decompositions:

  • 23 + 2147491837 = 2147491860
  • 29 + 2147491831 = 2147491860
  • 79 + 2147491781 = 2147491860
  • 103 + 2147491757 = 2147491860
  • 127 + 2147491733 = 2147491860
  • 251 + 2147491609 = 2147491860
  • 257 + 2147491603 = 2147491860
  • 263 + 2147491597 = 2147491860

Showing the first eight; more decompositions exist.
