Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616936, here are decompositions:

3 + 31616933 = 31616936
7 + 31616929 = 31616936
19 + 31616917 = 31616936
79 + 31616857 = 31616936
97 + 31616839 = 31616936
163 + 31616773 = 31616936
229 + 31616707 = 31616936
313 + 31616623 = 31616936

Showing the first eight; more decompositions exist.
