Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142918, here are decompositions:
- 11 + 142907 = 142918
- 47 + 142871 = 142918
- 107 + 142811 = 142918
- 131 + 142787 = 142918
- 311 + 142607 = 142918
- 317 + 142601 = 142918
- 359 + 142559 = 142918
- 389 + 142529 = 142918
Showing the first eight; more decompositions exist.
