Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576182, here are decompositions:

13 + 31576169 = 31576182
19 + 31576163 = 31576182
61 + 31576121 = 31576182
151 + 31576031 = 31576182
173 + 31576009 = 31576182
179 + 31576003 = 31576182
181 + 31576001 = 31576182
191 + 31575991 = 31576182

Showing the first eight; more decompositions exist.
