Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617166, here are decompositions:

17 + 31617149 = 31617166
89 + 31617077 = 31617166
137 + 31617029 = 31617166
167 + 31616999 = 31617166
179 + 31616987 = 31617166
233 + 31616933 = 31617166
263 + 31616903 = 31617166
419 + 31616747 = 31617166

Showing the first eight; more decompositions exist.
