Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606566, here are decompositions:

7 + 31606559 = 31606566
23 + 31606543 = 31606566
29 + 31606537 = 31606566
37 + 31606529 = 31606566
67 + 31606499 = 31606566
73 + 31606493 = 31606566
97 + 31606469 = 31606566
137 + 31606429 = 31606566

Showing the first eight; more decompositions exist.
