Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447046, here are decompositions:

3 + 31447043 = 31447046
19 + 31447027 = 31447046
73 + 31446973 = 31447046
97 + 31446949 = 31447046
109 + 31446937 = 31447046
193 + 31446853 = 31447046
199 + 31446847 = 31447046
277 + 31446769 = 31447046

Showing the first eight; more decompositions exist.
