Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617490, here are decompositions:

  • 43 + 8617447 = 8617490
  • 73 + 8617417 = 8617490
  • 109 + 8617381 = 8617490
  • 157 + 8617333 = 8617490
  • 163 + 8617327 = 8617490
  • 199 + 8617291 = 8617490
  • 229 + 8617261 = 8617490
  • 283 + 8617207 = 8617490

Showing the first eight; more decompositions exist.
