Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147484428, here are decompositions:

  • 79 + 2147484349 = 2147484428
  • 97 + 2147484331 = 2147484428
  • 151 + 2147484277 = 2147484428
  • 157 + 2147484271 = 2147484428
  • 367 + 2147484061 = 2147484428
  • 421 + 2147484007 = 2147484428
  • 499 + 2147483929 = 2147484428
  • 541 + 2147483887 = 2147484428

Showing the first eight; more decompositions exist.
