Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674688, here are decompositions:

  • 7 + 8674681 = 8674688
  • 151 + 8674537 = 8674688
  • 157 + 8674531 = 8674688
  • 199 + 8674489 = 8674688
  • 241 + 8674447 = 8674688
  • 349 + 8674339 = 8674688
  • 367 + 8674321 = 8674688
  • 439 + 8674249 = 8674688

Showing the first eight; more decompositions exist.
