Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664612, here are decompositions:

  • 31 + 8664581 = 8664612
  • 53 + 8664559 = 8664612
  • 59 + 8664553 = 8664612
  • 83 + 8664529 = 8664612
  • 139 + 8664473 = 8664612
  • 179 + 8664433 = 8664612
  • 181 + 8664431 = 8664612
  • 191 + 8664421 = 8664612

Showing the first eight; more decompositions exist.
