Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617192, here are decompositions:

11 + 31617181 = 31617192
43 + 31617149 = 31617192
59 + 31617133 = 31617192
163 + 31617029 = 31617192
179 + 31617013 = 31617192
181 + 31617011 = 31617192
193 + 31616999 = 31617192
241 + 31616951 = 31617192

Showing the first eight; more decompositions exist.
