Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30168, here are decompositions:
- 7 + 30161 = 30168
- 29 + 30139 = 30168
- 31 + 30137 = 30168
- 59 + 30109 = 30168
- 71 + 30097 = 30168
- 79 + 30089 = 30168
- 97 + 30071 = 30168
- 109 + 30059 = 30168
Showing the first eight; more decompositions exist.
