Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626794, here are decompositions:

7 + 31626787 = 31626794
103 + 31626691 = 31626794
127 + 31626667 = 31626794
223 + 31626571 = 31626794
313 + 31626481 = 31626794
373 + 31626421 = 31626794
457 + 31626337 = 31626794
547 + 31626247 = 31626794

Showing the first eight; more decompositions exist.
