Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497302, here are decompositions:

3 + 31497299 = 31497302
19 + 31497283 = 31497302
73 + 31497229 = 31497302
79 + 31497223 = 31497302
163 + 31497139 = 31497302
313 + 31496989 = 31497302
439 + 31496863 = 31497302
523 + 31496779 = 31497302

Showing the first eight; more decompositions exist.
