Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626906, here are decompositions:

7 + 31626899 = 31626906
13 + 31626893 = 31626906
23 + 31626883 = 31626906
37 + 31626869 = 31626906
67 + 31626839 = 31626906
79 + 31626827 = 31626906
109 + 31626797 = 31626906
139 + 31626767 = 31626906

Showing the first eight; more decompositions exist.
