Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142760, here are decompositions:
- 3 + 142757 = 142760
- 61 + 142699 = 142760
- 103 + 142657 = 142760
- 151 + 142609 = 142760
- 193 + 142567 = 142760
- 223 + 142537 = 142760
- 307 + 142453 = 142760
- 379 + 142381 = 142760
Showing the first eight; more decompositions exist.
