Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31602222, here are decompositions:

5 + 31602217 = 31602222
59 + 31602163 = 31602222
79 + 31602143 = 31602222
101 + 31602121 = 31602222
151 + 31602071 = 31602222
173 + 31602049 = 31602222
181 + 31602041 = 31602222
331 + 31601891 = 31602222

Showing the first eight; more decompositions exist.
