Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626600, here are decompositions:

11 + 31626589 = 31626600
29 + 31626571 = 31626600
37 + 31626563 = 31626600
43 + 31626557 = 31626600
53 + 31626547 = 31626600
67 + 31626533 = 31626600
101 + 31626499 = 31626600
107 + 31626493 = 31626600

Showing the first eight; more decompositions exist.
