Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576174, here are decompositions:

5 + 31576169 = 31576174
11 + 31576163 = 31576174
53 + 31576121 = 31576174
83 + 31576091 = 31576174
107 + 31576067 = 31576174
137 + 31576037 = 31576174
167 + 31576007 = 31576174
173 + 31576001 = 31576174

Showing the first eight; more decompositions exist.
