Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8686140, here are decompositions:

  • 13 + 8686127 = 8686140
  • 17 + 8686123 = 8686140
  • 19 + 8686121 = 8686140
  • 37 + 8686103 = 8686140
  • 53 + 8686087 = 8686140
  • 137 + 8686003 = 8686140
  • 139 + 8686001 = 8686140
  • 173 + 8685967 = 8686140

Showing the first eight; more decompositions exist.
