Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487912, here are decompositions:

  • 5 + 2147487907 = 2147487912
  • 13 + 2147487899 = 2147487912
  • 41 + 2147487871 = 2147487912
  • 43 + 2147487869 = 2147487912
  • 79 + 2147487833 = 2147487912
  • 83 + 2147487829 = 2147487912
  • 109 + 2147487803 = 2147487912
  • 113 + 2147487799 = 2147487912

Showing the first eight; more decompositions exist.
