Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605026, here are decompositions:

7 + 31605019 = 31605026
67 + 31604959 = 31605026
163 + 31604863 = 31605026
223 + 31604803 = 31605026
283 + 31604743 = 31605026
307 + 31604719 = 31605026
337 + 31604689 = 31605026
379 + 31604647 = 31605026

Showing the first eight; more decompositions exist.
