Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147579306, here are decompositions:

  • 43 + 2147579263 = 2147579306
  • 79 + 2147579227 = 2147579306
  • 97 + 2147579209 = 2147579306
  • 307 + 2147578999 = 2147579306
  • 349 + 2147578957 = 2147579306
  • 877 + 2147578429 = 2147579306
  • 1063 + 2147578243 = 2147579306
  • 1123 + 2147578183 = 2147579306

Showing the first eight; more decompositions exist.
