Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616994, here are decompositions:

7 + 31616987 = 31616994
43 + 31616951 = 31616994
61 + 31616933 = 31616994
103 + 31616891 = 31616994
107 + 31616887 = 31616994
137 + 31616857 = 31616994
307 + 31616687 = 31616994
317 + 31616677 = 31616994

Showing the first eight; more decompositions exist.
