Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606588, here are decompositions:

5 + 31606583 = 31606588
29 + 31606559 = 31606588
47 + 31606541 = 31606588
59 + 31606529 = 31606588
71 + 31606517 = 31606588
89 + 31606499 = 31606588
191 + 31606397 = 31606588
257 + 31606331 = 31606588

Showing the first eight; more decompositions exist.
