Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148122, here are decompositions:

31 + 148091 = 148122
43 + 148079 = 148122
59 + 148063 = 148122
61 + 148061 = 148122
101 + 148021 = 148122
109 + 148013 = 148122
173 + 147949 = 148122
241 + 147881 = 148122

Showing the first eight; more decompositions exist.
