Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147456932, here are decompositions:

  • 3 + 2147456929 = 2147456932
  • 29 + 2147456903 = 2147456932
  • 53 + 2147456879 = 2147456932
  • 239 + 2147456693 = 2147456932
  • 251 + 2147456681 = 2147456932
  • 311 + 2147456621 = 2147456932
  • 389 + 2147456543 = 2147456932
  • 431 + 2147456501 = 2147456932

Showing the first eight; more decompositions exist.
