Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491938, here are decompositions:

  • 41 + 2147491897 = 2147491938
  • 101 + 2147491837 = 2147491938
  • 107 + 2147491831 = 2147491938
  • 157 + 2147491781 = 2147491938
  • 181 + 2147491757 = 2147491938
  • 239 + 2147491699 = 2147491938
  • 331 + 2147491607 = 2147491938
  • 379 + 2147491559 = 2147491938

Showing the first eight; more decompositions exist.
