Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22118, here are decompositions:

7 + 22111 = 22118
67 + 22051 = 22118
79 + 22039 = 22118
127 + 21991 = 22118
157 + 21961 = 22118
181 + 21937 = 22118
277 + 21841 = 22118
331 + 21787 = 22118

Showing the first eight; more decompositions exist.
