Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142758, here are decompositions:
- 47 + 142711 = 142758
- 59 + 142699 = 142758
- 61 + 142697 = 142758
- 101 + 142657 = 142758
- 139 + 142619 = 142758
- 149 + 142609 = 142758
- 151 + 142607 = 142758
- 157 + 142601 = 142758
Showing the first eight; more decompositions exist.
