Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626328, here are decompositions:

5 + 31626323 = 31626328
131 + 31626197 = 31626328
137 + 31626191 = 31626328
197 + 31626131 = 31626328
317 + 31626011 = 31626328
347 + 31625981 = 31626328
359 + 31625969 = 31626328
389 + 31625939 = 31626328

Showing the first eight; more decompositions exist.
