Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31493056, here are decompositions:

3 + 31493053 = 31493056
17 + 31493039 = 31493056
47 + 31493009 = 31493056
59 + 31492997 = 31493056
113 + 31492943 = 31493056
149 + 31492907 = 31493056
197 + 31492859 = 31493056
359 + 31492697 = 31493056

Showing the first eight; more decompositions exist.
