Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626044, here are decompositions:

3 + 31626041 = 31626044
127 + 31625917 = 31626044
223 + 31625821 = 31626044
271 + 31625773 = 31626044
277 + 31625767 = 31626044
283 + 31625761 = 31626044
313 + 31625731 = 31626044
397 + 31625647 = 31626044

Showing the first eight; more decompositions exist.
