Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142732, here are decompositions:
- 59 + 142673 = 142732
- 113 + 142619 = 142732
- 131 + 142601 = 142732
- 173 + 142559 = 142732
- 179 + 142553 = 142732
- 263 + 142469 = 142732
- 311 + 142421 = 142732
- 461 + 142271 = 142732
Showing the first eight; more decompositions exist.
