Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659390, here are decompositions:

  • 101 + 8659289 = 8659390
  • 167 + 8659223 = 8659390
  • 269 + 8659121 = 8659390
  • 293 + 8659097 = 8659390
  • 347 + 8659043 = 8659390
  • 353 + 8659037 = 8659390
  • 401 + 8658989 = 8659390
  • 431 + 8658959 = 8659390

Showing the first eight; more decompositions exist.
