Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147527774, here are decompositions:

  • 17 + 2147527757 = 2147527774
  • 191 + 2147527583 = 2147527774
  • 347 + 2147527427 = 2147527774
  • 401 + 2147527373 = 2147527774
  • 443 + 2147527331 = 2147527774
  • 617 + 2147527157 = 2147527774
  • 647 + 2147527127 = 2147527774
  • 773 + 2147527001 = 2147527774

Showing the first eight; more decompositions exist.
