Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626910, here are decompositions:

11 + 31626899 = 31626910
17 + 31626893 = 31626910
41 + 31626869 = 31626910
53 + 31626857 = 31626910
71 + 31626839 = 31626910
83 + 31626827 = 31626910
113 + 31626797 = 31626910
347 + 31626563 = 31626910

Showing the first eight; more decompositions exist.
