Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628518, here are decompositions:

  • 37 + 8628481 = 8628518
  • 97 + 8628421 = 8628518
  • 331 + 8628187 = 8628518
  • 337 + 8628181 = 8628518
  • 397 + 8628121 = 8628518
  • 421 + 8628097 = 8628518
  • 487 + 8628031 = 8628518
  • 499 + 8628019 = 8628518

Showing the first eight; more decompositions exist.
