Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626050, here are decompositions:

31 + 31626019 = 31626050
97 + 31625953 = 31626050
139 + 31625911 = 31626050
229 + 31625821 = 31626050
271 + 31625779 = 31626050
277 + 31625773 = 31626050
283 + 31625767 = 31626050
397 + 31625653 = 31626050

Showing the first eight; more decompositions exist.
