Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626570, here are decompositions:

7 + 31626563 = 31626570
13 + 31626557 = 31626570
23 + 31626547 = 31626570
37 + 31626533 = 31626570
71 + 31626499 = 31626570
89 + 31626481 = 31626570
109 + 31626461 = 31626570
149 + 31626421 = 31626570

Showing the first eight; more decompositions exist.
