Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646558, here are decompositions:

  • 29 + 8646529 = 8646558
  • 47 + 8646511 = 8646558
  • 61 + 8646497 = 8646558
  • 71 + 8646487 = 8646558
  • 79 + 8646479 = 8646558
  • 101 + 8646457 = 8646558
  • 157 + 8646401 = 8646558
  • 181 + 8646377 = 8646558

Showing the first eight; more decompositions exist.
