Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616954, here are decompositions:

3 + 31616951 = 31616954
37 + 31616917 = 31616954
67 + 31616887 = 31616954
97 + 31616857 = 31616954
181 + 31616773 = 31616954
277 + 31616677 = 31616954
283 + 31616671 = 31616954
307 + 31616647 = 31616954

Showing the first eight; more decompositions exist.
