Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645492, here are decompositions:

  • 43 + 8645449 = 8645492
  • 61 + 8645431 = 8645492
  • 139 + 8645353 = 8645492
  • 151 + 8645341 = 8645492
  • 199 + 8645293 = 8645492
  • 211 + 8645281 = 8645492
  • 223 + 8645269 = 8645492
  • 313 + 8645179 = 8645492

Showing the first eight; more decompositions exist.
