Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8685198, here are decompositions:

  • 31 + 8685167 = 8685198
  • 37 + 8685161 = 8685198
  • 47 + 8685151 = 8685198
  • 157 + 8685041 = 8685198
  • 167 + 8685031 = 8685198
  • 239 + 8684959 = 8685198
  • 251 + 8684947 = 8685198
  • 257 + 8684941 = 8685198

Showing the first eight; more decompositions exist.
