Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491084, here are decompositions:

  • 3 + 2147491081 = 2147491084
  • 17 + 2147491067 = 2147491084
  • 23 + 2147491061 = 2147491084
  • 41 + 2147491043 = 2147491084
  • 47 + 2147491037 = 2147491084
  • 83 + 2147491001 = 2147491084
  • 131 + 2147490953 = 2147491084
  • 251 + 2147490833 = 2147491084

Showing the first eight; more decompositions exist.
