Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142960, here are decompositions:
- 11 + 142949 = 142960
- 53 + 142907 = 142960
- 89 + 142871 = 142960
- 149 + 142811 = 142960
- 173 + 142787 = 142960
- 227 + 142733 = 142960
- 263 + 142697 = 142960
- 353 + 142607 = 142960
Showing the first eight; more decompositions exist.
