Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 12120, here are decompositions:

7 + 12113 = 12120
11 + 12109 = 12120
13 + 12107 = 12120
19 + 12101 = 12120
23 + 12097 = 12120
47 + 12073 = 12120
71 + 12049 = 12120
79 + 12041 = 12120

Showing the first eight; more decompositions exist.
