Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669088, here are decompositions:

  • 5 + 8669083 = 8669088
  • 17 + 8669071 = 8669088
  • 47 + 8669041 = 8669088
  • 61 + 8669027 = 8669088
  • 137 + 8668951 = 8669088
  • 191 + 8668897 = 8669088
  • 199 + 8668889 = 8669088
  • 251 + 8668837 = 8669088

Showing the first eight; more decompositions exist.
