Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142680, here are decompositions:
- 7 + 142673 = 142680
- 23 + 142657 = 142680
- 61 + 142619 = 142680
- 71 + 142609 = 142680
- 73 + 142607 = 142680
- 79 + 142601 = 142680
- 89 + 142591 = 142680
- 107 + 142573 = 142680
Showing the first eight; more decompositions exist.
