Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626856, here are decompositions:

17 + 31626839 = 31626856
29 + 31626827 = 31626856
59 + 31626797 = 31626856
89 + 31626767 = 31626856
167 + 31626689 = 31626856
293 + 31626563 = 31626856
419 + 31626437 = 31626856
449 + 31626407 = 31626856

Showing the first eight; more decompositions exist.
