Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142406, here are decompositions:
- 3 + 142403 = 142406
- 37 + 142369 = 142406
- 79 + 142327 = 142406
- 109 + 142297 = 142406
- 223 + 142183 = 142406
- 283 + 142123 = 142406
- 307 + 142099 = 142406
- 349 + 142057 = 142406
Showing the first eight; more decompositions exist.
