Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30118, here are decompositions:
- 5 + 30113 = 30118
- 29 + 30089 = 30118
- 47 + 30071 = 30118
- 59 + 30059 = 30118
- 71 + 30047 = 30118
- 89 + 30029 = 30118
- 107 + 30011 = 30118
- 191 + 29927 = 30118
Showing the first eight; more decompositions exist.
