Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147499780, here are decompositions:

  • 53 + 2147499727 = 2147499780
  • 73 + 2147499707 = 2147499780
  • 109 + 2147499671 = 2147499780
  • 163 + 2147499617 = 2147499780
  • 233 + 2147499547 = 2147499780
  • 241 + 2147499539 = 2147499780
  • 269 + 2147499511 = 2147499780
  • 271 + 2147499509 = 2147499780

Showing the first eight; more decompositions exist.
