Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649430, here are decompositions:

  • 11 + 8649419 = 8649430
  • 47 + 8649383 = 8649430
  • 59 + 8649371 = 8649430
  • 107 + 8649323 = 8649430
  • 113 + 8649317 = 8649430
  • 131 + 8649299 = 8649430
  • 137 + 8649293 = 8649430
  • 191 + 8649239 = 8649430

Showing the first eight; more decompositions exist.
