Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616996, here are decompositions:

67 + 31616929 = 31616996
79 + 31616917 = 31616996
109 + 31616887 = 31616996
139 + 31616857 = 31616996
157 + 31616839 = 31616996
223 + 31616773 = 31616996
349 + 31616647 = 31616996
373 + 31616623 = 31616996

Showing the first eight; more decompositions exist.
