Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142346, here are decompositions:
- 19 + 142327 = 142346
- 109 + 142237 = 142346
- 157 + 142189 = 142346
- 163 + 142183 = 142346
- 223 + 142123 = 142346
- 307 + 142039 = 142346
- 409 + 141937 = 142346
- 439 + 141907 = 142346
Showing the first eight; more decompositions exist.
