Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446026, here are decompositions:

43 + 31445983 = 31446026
67 + 31445959 = 31446026
97 + 31445929 = 31446026
109 + 31445917 = 31446026
163 + 31445863 = 31446026
193 + 31445833 = 31446026
307 + 31445719 = 31446026
349 + 31445677 = 31446026

Showing the first eight; more decompositions exist.
