Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597526, here are decompositions:

19 + 31597507 = 31597526
43 + 31597483 = 31597526
73 + 31597453 = 31597526
109 + 31597417 = 31597526
283 + 31597243 = 31597526
313 + 31597213 = 31597526
349 + 31597177 = 31597526
397 + 31597129 = 31597526

Showing the first eight; more decompositions exist.
