Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616050, here are decompositions:

3 + 31616047 = 31616050
17 + 31616033 = 31616050
29 + 31616021 = 31616050
41 + 31616009 = 31616050
71 + 31615979 = 31616050
131 + 31615919 = 31616050
293 + 31615757 = 31616050
461 + 31615589 = 31616050

Showing the first eight; more decompositions exist.
