Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142286, here are decompositions:
- 97 + 142189 = 142286
- 103 + 142183 = 142286
- 127 + 142159 = 142286
- 163 + 142123 = 142286
- 229 + 142057 = 142286
- 349 + 141937 = 142286
- 379 + 141907 = 142286
- 433 + 141853 = 142286
Showing the first eight; more decompositions exist.
