Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426100, here are decompositions:

  • 19 + 2147426081 = 2147426100
  • 47 + 2147426053 = 2147426100
  • 97 + 2147426003 = 2147426100
  • 107 + 2147425993 = 2147426100
  • 163 + 2147425937 = 2147426100
  • 167 + 2147425933 = 2147426100
  • 229 + 2147425871 = 2147426100
  • 389 + 2147425711 = 2147426100

Showing the first eight; more decompositions exist.
