Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661338, here are decompositions:

  • 97 + 8661241 = 8661338
  • 157 + 8661181 = 8661338
  • 277 + 8661061 = 8661338
  • 337 + 8661001 = 8661338
  • 409 + 8660929 = 8661338
  • 541 + 8660797 = 8661338
  • 571 + 8660767 = 8661338
  • 727 + 8660611 = 8661338

Showing the first eight; more decompositions exist.
