Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142274, here are decompositions:
- 3 + 142271 = 142274
- 37 + 142237 = 142274
- 43 + 142231 = 142274
- 151 + 142123 = 142274
- 163 + 142111 = 142274
- 283 + 141991 = 142274
- 313 + 141961 = 142274
- 337 + 141937 = 142274
Showing the first eight; more decompositions exist.
