Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156120, here are decompositions:

11 + 156109 = 156120
31 + 156089 = 156120
59 + 156061 = 156120
61 + 156059 = 156120
79 + 156041 = 156120
101 + 156019 = 156120
109 + 156011 = 156120
113 + 156007 = 156120

Showing the first eight; more decompositions exist.
