Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661424, here are decompositions:

  • 11 + 8661413 = 8661424
  • 17 + 8661407 = 8661424
  • 41 + 8661383 = 8661424
  • 71 + 8661353 = 8661424
  • 113 + 8661311 = 8661424
  • 173 + 8661251 = 8661424
  • 227 + 8661197 = 8661424
  • 251 + 8661173 = 8661424

Showing the first eight; more decompositions exist.
