Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 993168, here are decompositions:
- 31 + 993137 = 993168
- 47 + 993121 = 993168
- 61 + 993107 = 993168
- 89 + 993079 = 993168
- 131 + 993037 = 993168
- 157 + 993011 = 993168
- 167 + 993001 = 993168
- 227 + 992941 = 993168
Showing the first eight; more decompositions exist.
