Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620958, here are decompositions:

11 + 31620947 = 31620958
137 + 31620821 = 31620958
179 + 31620779 = 31620958
359 + 31620599 = 31620958
389 + 31620569 = 31620958
461 + 31620497 = 31620958
599 + 31620359 = 31620958
641 + 31620317 = 31620958

Showing the first eight; more decompositions exist.
