Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8757938, here are decompositions:

  • 19 + 8757919 = 8757938
  • 61 + 8757877 = 8757938
  • 109 + 8757829 = 8757938
  • 139 + 8757799 = 8757938
  • 181 + 8757757 = 8757938
  • 367 + 8757571 = 8757938
  • 421 + 8757517 = 8757938
  • 661 + 8757277 = 8757938

Showing the first eight; more decompositions exist.
