Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147427886, here are decompositions:

  • 3 + 2147427883 = 2147427886
  • 47 + 2147427839 = 2147427886
  • 59 + 2147427827 = 2147427886
  • 89 + 2147427797 = 2147427886
  • 239 + 2147427647 = 2147427886
  • 293 + 2147427593 = 2147427886
  • 677 + 2147427209 = 2147427886
  • 839 + 2147427047 = 2147427886

Showing the first eight; more decompositions exist.
