Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628120, here are decompositions:
- 13 + 8628107 = 8628120
- 23 + 8628097 = 8628120
- 43 + 8628077 = 8628120
- 71 + 8628049 = 8628120
- 89 + 8628031 = 8628120
- 101 + 8628019 = 8628120
- 103 + 8628017 = 8628120
- 113 + 8628007 = 8628120
Showing the first eight; more decompositions exist.
