Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8708978, here are decompositions:

  • 7 + 8708971 = 8708978
  • 67 + 8708911 = 8708978
  • 277 + 8708701 = 8708978
  • 367 + 8708611 = 8708978
  • 457 + 8708521 = 8708978
  • 709 + 8708269 = 8708978
  • 877 + 8708101 = 8708978
  • 907 + 8708071 = 8708978

Showing the first eight; more decompositions exist.
