Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422708, here are decompositions:
- 5 + 2147422703 = 2147422708
- 17 + 2147422691 = 2147422708
- 29 + 2147422679 = 2147422708
- 59 + 2147422649 = 2147422708
- 149 + 2147422559 = 2147422708
- 227 + 2147422481 = 2147422708
- 251 + 2147422457 = 2147422708
- 467 + 2147422241 = 2147422708
Showing the first eight; more decompositions exist.
