Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142968, here are decompositions:
- 5 + 142963 = 142968
- 19 + 142949 = 142968
- 29 + 142939 = 142968
- 61 + 142907 = 142968
- 71 + 142897 = 142968
- 97 + 142871 = 142968
- 101 + 142867 = 142968
- 127 + 142841 = 142968
Showing the first eight; more decompositions exist.
