Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147453086, here are decompositions:

  • 5 + 2147453081 = 2147453086
  • 29 + 2147453057 = 2147453086
  • 113 + 2147452973 = 2147453086
  • 137 + 2147452949 = 2147453086
  • 239 + 2147452847 = 2147453086
  • 293 + 2147452793 = 2147453086
  • 599 + 2147452487 = 2147453086
  • 617 + 2147452469 = 2147453086

Showing the first eight; more decompositions exist.
