Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617068, here are decompositions:

19 + 31617049 = 31617068
139 + 31616929 = 31617068
151 + 31616917 = 31617068
181 + 31616887 = 31617068
211 + 31616857 = 31617068
229 + 31616839 = 31617068
397 + 31616671 = 31617068
421 + 31616647 = 31617068

Showing the first eight; more decompositions exist.
