Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626062, here are decompositions:

43 + 31626019 = 31626062
109 + 31625953 = 31626062
151 + 31625911 = 31626062
241 + 31625821 = 31626062
283 + 31625779 = 31626062
331 + 31625731 = 31626062
409 + 31625653 = 31626062
463 + 31625599 = 31626062

Showing the first eight; more decompositions exist.
