Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142736, here are decompositions:
- 3 + 142733 = 142736
- 37 + 142699 = 142736
- 79 + 142657 = 142736
- 127 + 142609 = 142736
- 163 + 142573 = 142736
- 193 + 142543 = 142736
- 199 + 142537 = 142736
- 283 + 142453 = 142736
Showing the first eight; more decompositions exist.
