Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628180, here are decompositions:

  • 7 + 8628173 = 8628180
  • 19 + 8628161 = 8628180
  • 23 + 8628157 = 8628180
  • 31 + 8628149 = 8628180
  • 59 + 8628121 = 8628180
  • 73 + 8628107 = 8628180
  • 83 + 8628097 = 8628180
  • 103 + 8628077 = 8628180

Showing the first eight; more decompositions exist.
