Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31621060, here are decompositions:

17 + 31621043 = 31621060
47 + 31621013 = 31621060
59 + 31621001 = 31621060
113 + 31620947 = 31621060
239 + 31620821 = 31621060
281 + 31620779 = 31621060
311 + 31620749 = 31621060
461 + 31620599 = 31621060

Showing the first eight; more decompositions exist.
