Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590164, here are decompositions:

3 + 31590161 = 31590164
31 + 31590133 = 31590164
43 + 31590121 = 31590164
103 + 31590061 = 31590164
127 + 31590037 = 31590164
157 + 31590007 = 31590164
181 + 31589983 = 31590164
211 + 31589953 = 31590164

Showing the first eight; more decompositions exist.
