Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147584266, here are decompositions:

  • 7 + 2147584259 = 2147584266
  • 13 + 2147584253 = 2147584266
  • 17 + 2147584249 = 2147584266
  • 109 + 2147584157 = 2147584266
  • 197 + 2147584069 = 2147584266
  • 277 + 2147583989 = 2147584266
  • 283 + 2147583983 = 2147584266
  • 433 + 2147583833 = 2147584266

Showing the first eight; more decompositions exist.
