Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426040, here are decompositions:

  • 37 + 2147426003 = 2147426040
  • 47 + 2147425993 = 2147426040
  • 61 + 2147425979 = 2147426040
  • 103 + 2147425937 = 2147426040
  • 107 + 2147425933 = 2147426040
  • 281 + 2147425759 = 2147426040
  • 311 + 2147425729 = 2147426040
  • 359 + 2147425681 = 2147426040

Showing the first eight; more decompositions exist.
