Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493202, here are decompositions:

11 + 31493191 = 31493202
31 + 31493171 = 31493202
71 + 31493131 = 31493202
149 + 31493053 = 31493202
163 + 31493039 = 31493202
173 + 31493029 = 31493202
193 + 31493009 = 31493202
211 + 31492991 = 31493202

Showing the first eight; more decompositions exist.
