Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668388, here are decompositions:
- 7 + 8668381 = 8668388
- 19 + 8668369 = 8668388
- 31 + 8668357 = 8668388
- 109 + 8668279 = 8668388
- 181 + 8668207 = 8668388
- 277 + 8668111 = 8668388
- 307 + 8668081 = 8668388
- 331 + 8668057 = 8668388
Showing the first eight; more decompositions exist.
