Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31597402, here are decompositions:

149 + 31597253 = 31597402
251 + 31597151 = 31597402
281 + 31597121 = 31597402
359 + 31597043 = 31597402
479 + 31596923 = 31597402
503 + 31596899 = 31597402
521 + 31596881 = 31597402
563 + 31596839 = 31597402

Showing the first eight; more decompositions exist.
