Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31446956, here are decompositions:

3 + 31446953 = 31446956
7 + 31446949 = 31446956
19 + 31446937 = 31446956
97 + 31446859 = 31446956
103 + 31446853 = 31446956
109 + 31446847 = 31446956
199 + 31446757 = 31446956
349 + 31446607 = 31446956

Showing the first eight; more decompositions exist.
