Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163212, here are decompositions:
- 13 + 163199 = 163212
- 19 + 163193 = 163212
- 31 + 163181 = 163212
- 41 + 163171 = 163212
- 43 + 163169 = 163212
- 61 + 163151 = 163212
- 83 + 163129 = 163212
- 103 + 163109 = 163212
Showing the first eight; more decompositions exist.
