Goldbach decomposition

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.
