Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497804, here are decompositions:

  • 47 + 2147497757 = 2147497804
  • 71 + 2147497733 = 2147497804
  • 107 + 2147497697 = 2147497804
  • 113 + 2147497691 = 2147497804
  • 233 + 2147497571 = 2147497804
  • 281 + 2147497523 = 2147497804
  • 311 + 2147497493 = 2147497804
  • 401 + 2147497403 = 2147497804

Showing the first eight; more decompositions exist.
