Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497362, here are decompositions:

3 + 31497359 = 31497362
79 + 31497283 = 31497362
139 + 31497223 = 31497362
223 + 31497139 = 31497362
229 + 31497133 = 31497362
373 + 31496989 = 31497362
499 + 31496863 = 31497362
571 + 31496791 = 31497362

Showing the first eight; more decompositions exist.
