Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626058, here are decompositions:

5 + 31626053 = 31626058
17 + 31626041 = 31626058
47 + 31626011 = 31626058
71 + 31625987 = 31626058
89 + 31625969 = 31626058
239 + 31625819 = 31626058
251 + 31625807 = 31626058
281 + 31625777 = 31626058

Showing the first eight; more decompositions exist.
