Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616950, here are decompositions:

17 + 31616933 = 31616950
47 + 31616903 = 31616950
59 + 31616891 = 31616950
257 + 31616693 = 31616950
263 + 31616687 = 31616950
347 + 31616603 = 31616950
389 + 31616561 = 31616950
557 + 31616393 = 31616950

Showing the first eight; more decompositions exist.
