Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8655540, here are decompositions:

  • 13 + 8655527 = 8655540
  • 43 + 8655497 = 8655540
  • 83 + 8655457 = 8655540
  • 107 + 8655433 = 8655540
  • 137 + 8655403 = 8655540
  • 139 + 8655401 = 8655540
  • 191 + 8655349 = 8655540
  • 197 + 8655343 = 8655540

Showing the first eight; more decompositions exist.
