Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618318, here are decompositions:

  • 31 + 8618287 = 8618318
  • 61 + 8618257 = 8618318
  • 67 + 8618251 = 8618318
  • 97 + 8618221 = 8618318
  • 199 + 8618119 = 8618318
  • 211 + 8618107 = 8618318
  • 229 + 8618089 = 8618318
  • 271 + 8618047 = 8618318

Showing the first eight; more decompositions exist.
