Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584806, here are decompositions:

  • 109 + 2147584697 = 2147584806
  • 113 + 2147584693 = 2147584806
  • 127 + 2147584679 = 2147584806
  • 137 + 2147584669 = 2147584806
  • 149 + 2147584657 = 2147584806
  • 197 + 2147584609 = 2147584806
  • 277 + 2147584529 = 2147584806
  • 349 + 2147584457 = 2147584806

Showing the first eight; more decompositions exist.
