Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31515196, here are decompositions:

3 + 31515193 = 31515196
17 + 31515179 = 31515196
47 + 31515149 = 31515196
59 + 31515137 = 31515196
149 + 31515047 = 31515196
173 + 31515023 = 31515196
197 + 31514999 = 31515196
227 + 31514969 = 31515196

Showing the first eight; more decompositions exist.
