Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40122, here are decompositions:

11 + 40111 = 40122
23 + 40099 = 40122
29 + 40093 = 40122
59 + 40063 = 40122
83 + 40039 = 40122
109 + 40013 = 40122
113 + 40009 = 40122
139 + 39983 = 40122

Showing the first eight; more decompositions exist.
