Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616946, here are decompositions:

13 + 31616933 = 31616946
17 + 31616929 = 31616946
29 + 31616917 = 31616946
43 + 31616903 = 31616946
59 + 31616887 = 31616946
89 + 31616857 = 31616946
107 + 31616839 = 31616946
173 + 31616773 = 31616946

Showing the first eight; more decompositions exist.
