Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626566, here are decompositions:

3 + 31626563 = 31626566
19 + 31626547 = 31626566
67 + 31626499 = 31626566
73 + 31626493 = 31626566
199 + 31626367 = 31626566
229 + 31626337 = 31626566
337 + 31626229 = 31626566
373 + 31626193 = 31626566

Showing the first eight; more decompositions exist.
