Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623026, here are decompositions:

3 + 31623023 = 31623026
67 + 31622959 = 31623026
79 + 31622947 = 31623026
103 + 31622923 = 31623026
163 + 31622863 = 31623026
223 + 31622803 = 31623026
283 + 31622743 = 31623026
313 + 31622713 = 31623026

Showing the first eight; more decompositions exist.
