Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30108, here are decompositions:
- 5 + 30103 = 30108
- 11 + 30097 = 30108
- 17 + 30091 = 30108
- 19 + 30089 = 30108
- 37 + 30071 = 30108
- 61 + 30047 = 30108
- 79 + 30029 = 30108
- 97 + 30011 = 30108
Showing the first eight; more decompositions exist.
