Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147422498, here are decompositions:
- 5 + 2147422493 = 2147422498
- 17 + 2147422481 = 2147422498
- 41 + 2147422457 = 2147422498
- 167 + 2147422331 = 2147422498
- 227 + 2147422271 = 2147422498
- 257 + 2147422241 = 2147422498
- 269 + 2147422229 = 2147422498
- 359 + 2147422139 = 2147422498
Showing the first eight; more decompositions exist.
