Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626934, here are decompositions:

41 + 31626893 = 31626934
107 + 31626827 = 31626934
137 + 31626797 = 31626934
167 + 31626767 = 31626934
401 + 31626533 = 31626934
557 + 31626377 = 31626934
701 + 31626233 = 31626934
743 + 31626191 = 31626934

Showing the first eight; more decompositions exist.
