Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8758978, here are decompositions:

  • 47 + 8758931 = 8758978
  • 89 + 8758889 = 8758978
  • 101 + 8758877 = 8758978
  • 131 + 8758847 = 8758978
  • 191 + 8758787 = 8758978
  • 197 + 8758781 = 8758978
  • 257 + 8758721 = 8758978
  • 281 + 8758697 = 8758978

Showing the first eight; more decompositions exist.
