Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30120, here are decompositions:
- 7 + 30113 = 30120
- 11 + 30109 = 30120
- 17 + 30103 = 30120
- 23 + 30097 = 30120
- 29 + 30091 = 30120
- 31 + 30089 = 30120
- 61 + 30059 = 30120
- 73 + 30047 = 30120
Showing the first eight; more decompositions exist.
