Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142422, here are decompositions:
- 19 + 142403 = 142422
- 31 + 142391 = 142422
- 41 + 142381 = 142422
- 53 + 142369 = 142422
- 103 + 142319 = 142422
- 151 + 142271 = 142422
- 191 + 142231 = 142422
- 199 + 142223 = 142422
Showing the first eight; more decompositions exist.
