Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712290, here are decompositions:

  • 3 + 8712287 = 8712290
  • 31 + 8712259 = 8712290
  • 61 + 8712229 = 8712290
  • 109 + 8712181 = 8712290
  • 127 + 8712163 = 8712290
  • 157 + 8712133 = 8712290
  • 199 + 8712091 = 8712290
  • 271 + 8712019 = 8712290

Showing the first eight; more decompositions exist.
