Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491568, here are decompositions:

  • 31 + 2147491537 = 2147491568
  • 151 + 2147491417 = 2147491568
  • 199 + 2147491369 = 2147491568
  • 307 + 2147491261 = 2147491568
  • 331 + 2147491237 = 2147491568
  • 349 + 2147491219 = 2147491568
  • 367 + 2147491201 = 2147491568
  • 457 + 2147491111 = 2147491568

Showing the first eight; more decompositions exist.
