Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143212, here are decompositions:
- 53 + 143159 = 143212
- 71 + 143141 = 143212
- 101 + 143111 = 143212
- 149 + 143063 = 143212
- 233 + 142979 = 143212
- 239 + 142973 = 143212
- 263 + 142949 = 143212
- 401 + 142811 = 143212
Showing the first eight; more decompositions exist.
