Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750978, here are decompositions:

  • 31 + 8750947 = 8750978
  • 37 + 8750941 = 8750978
  • 97 + 8750881 = 8750978
  • 241 + 8750737 = 8750978
  • 277 + 8750701 = 8750978
  • 337 + 8750641 = 8750978
  • 487 + 8750491 = 8750978
  • 499 + 8750479 = 8750978

Showing the first eight; more decompositions exist.
