Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597286, here are decompositions:

3 + 31597283 = 31597286
43 + 31597243 = 31597286
73 + 31597213 = 31597286
109 + 31597177 = 31597286
157 + 31597129 = 31597286
283 + 31597003 = 31597286
337 + 31596949 = 31597286
373 + 31596913 = 31597286

Showing the first eight; more decompositions exist.
