Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534122, here are decompositions:

5 + 31534117 = 31534122
19 + 31534103 = 31534122
43 + 31534079 = 31534122
71 + 31534051 = 31534122
89 + 31534033 = 31534122
163 + 31533959 = 31534122
173 + 31533949 = 31534122
199 + 31533923 = 31534122

Showing the first eight; more decompositions exist.
