Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617026, here are decompositions:

3 + 31617023 = 31617026
13 + 31617013 = 31617026
97 + 31616929 = 31617026
109 + 31616917 = 31617026
139 + 31616887 = 31617026
277 + 31616749 = 31617026
349 + 31616677 = 31617026
379 + 31616647 = 31617026

Showing the first eight; more decompositions exist.
