Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664390, here are decompositions:

  • 13 + 8664377 = 8664390
  • 23 + 8664367 = 8664390
  • 61 + 8664329 = 8664390
  • 73 + 8664317 = 8664390
  • 79 + 8664311 = 8664390
  • 131 + 8664259 = 8664390
  • 167 + 8664223 = 8664390
  • 197 + 8664193 = 8664390

Showing the first eight; more decompositions exist.
