Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447058, here are decompositions:

31 + 31447027 = 31447058
37 + 31447021 = 31447058
61 + 31446997 = 31447058
109 + 31446949 = 31447058
199 + 31446859 = 31447058
211 + 31446847 = 31447058
619 + 31446439 = 31447058
631 + 31446427 = 31447058

Showing the first eight; more decompositions exist.
