Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617196, here are decompositions:

29 + 31617167 = 31617196
47 + 31617149 = 31617196
167 + 31617029 = 31617196
173 + 31617023 = 31617196
197 + 31616999 = 31617196
263 + 31616933 = 31617196
293 + 31616903 = 31617196
449 + 31616747 = 31617196

Showing the first eight; more decompositions exist.
