Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142192, here are decompositions:
- 3 + 142189 = 142192
- 23 + 142169 = 142192
- 41 + 142151 = 142192
- 131 + 142061 = 142192
- 173 + 142019 = 142192
- 233 + 141959 = 142192
- 251 + 141941 = 142192
- 359 + 141833 = 142192
Showing the first eight; more decompositions exist.
