Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659890, here are decompositions:

  • 17 + 8659873 = 8659890
  • 23 + 8659867 = 8659890
  • 53 + 8659837 = 8659890
  • 79 + 8659811 = 8659890
  • 97 + 8659793 = 8659890
  • 149 + 8659741 = 8659890
  • 179 + 8659711 = 8659890
  • 199 + 8659691 = 8659890

Showing the first eight; more decompositions exist.
