Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7122, here are decompositions:

13 + 7109 = 7122
19 + 7103 = 7122
43 + 7079 = 7122
53 + 7069 = 7122
79 + 7043 = 7122
83 + 7039 = 7122
103 + 7019 = 7122
109 + 7013 = 7122

Showing the first eight; more decompositions exist.
