Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147426290, here are decompositions:

  • 47 + 2147426243 = 2147426290
  • 83 + 2147426207 = 2147426290
  • 131 + 2147426159 = 2147426290
  • 137 + 2147426153 = 2147426290
  • 173 + 2147426117 = 2147426290
  • 311 + 2147425979 = 2147426290
  • 353 + 2147425937 = 2147426290
  • 419 + 2147425871 = 2147426290

Showing the first eight; more decompositions exist.
