Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626446, here are decompositions:

79 + 31626367 = 31626446
109 + 31626337 = 31626446
199 + 31626247 = 31626446
337 + 31626109 = 31626446
367 + 31626079 = 31626446
373 + 31626073 = 31626446
673 + 31625773 = 31626446
829 + 31625617 = 31626446

Showing the first eight; more decompositions exist.
