Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616906, here are decompositions:

3 + 31616903 = 31616906
19 + 31616887 = 31616906
67 + 31616839 = 31616906
157 + 31616749 = 31616906
199 + 31616707 = 31616906
229 + 31616677 = 31616906
283 + 31616623 = 31616906
337 + 31616569 = 31616906

Showing the first eight; more decompositions exist.
