Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626674, here are decompositions:

7 + 31626667 = 31626674
67 + 31626607 = 31626674
103 + 31626571 = 31626674
127 + 31626547 = 31626674
181 + 31626493 = 31626674
193 + 31626481 = 31626674
307 + 31626367 = 31626674
337 + 31626337 = 31626674

Showing the first eight; more decompositions exist.
