Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626574, here are decompositions:

3 + 31626571 = 31626574
11 + 31626563 = 31626574
17 + 31626557 = 31626574
41 + 31626533 = 31626574
113 + 31626461 = 31626574
137 + 31626437 = 31626574
167 + 31626407 = 31626574
191 + 31626383 = 31626574

Showing the first eight; more decompositions exist.
