Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30130, here are decompositions:
- 11 + 30119 = 30130
- 17 + 30113 = 30130
- 41 + 30089 = 30130
- 59 + 30071 = 30130
- 71 + 30059 = 30130
- 83 + 30047 = 30130
- 101 + 30029 = 30130
- 251 + 29879 = 30130
Showing the first eight; more decompositions exist.
