Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661370, here are decompositions:

  • 17 + 8661353 = 8661370
  • 59 + 8661311 = 8661370
  • 89 + 8661281 = 8661370
  • 131 + 8661239 = 8661370
  • 167 + 8661203 = 8661370
  • 173 + 8661197 = 8661370
  • 197 + 8661173 = 8661370
  • 233 + 8661137 = 8661370

Showing the first eight; more decompositions exist.
