Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 28122, here are decompositions:

11 + 28111 = 28122
13 + 28109 = 28122
23 + 28099 = 28122
41 + 28081 = 28122
53 + 28069 = 28122
71 + 28051 = 28122
103 + 28019 = 28122
139 + 27983 = 28122

Showing the first eight; more decompositions exist.
