Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742398, here are decompositions:

  • 19 + 8742379 = 8742398
  • 31 + 8742367 = 8742398
  • 139 + 8742259 = 8742398
  • 211 + 8742187 = 8742398
  • 229 + 8742169 = 8742398
  • 241 + 8742157 = 8742398
  • 277 + 8742121 = 8742398
  • 331 + 8742067 = 8742398

Showing the first eight; more decompositions exist.
