Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617442, here are decompositions:

  • 3 + 8617439 = 8617442
  • 61 + 8617381 = 8617442
  • 109 + 8617333 = 8617442
  • 151 + 8617291 = 8617442
  • 181 + 8617261 = 8617442
  • 241 + 8617201 = 8617442
  • 271 + 8617171 = 8617442
  • 313 + 8617129 = 8617442

Showing the first eight; more decompositions exist.
