Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626526, here are decompositions:

89 + 31626437 = 31626526
137 + 31626389 = 31626526
149 + 31626377 = 31626526
167 + 31626359 = 31626526
293 + 31626233 = 31626526
317 + 31626209 = 31626526
359 + 31626167 = 31626526
557 + 31625969 = 31626526

Showing the first eight; more decompositions exist.
