Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147399544, here are decompositions:

  • 11 + 2147399533 = 2147399544
  • 23 + 2147399521 = 2147399544
  • 53 + 2147399491 = 2147399544
  • 83 + 2147399461 = 2147399544
  • 97 + 2147399447 = 2147399544
  • 113 + 2147399431 = 2147399544
  • 137 + 2147399407 = 2147399544
  • 163 + 2147399381 = 2147399544

Showing the first eight; more decompositions exist.
