Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447016, here are decompositions:

19 + 31446997 = 31447016
43 + 31446973 = 31447016
67 + 31446949 = 31447016
79 + 31446937 = 31447016
157 + 31446859 = 31447016
163 + 31446853 = 31447016
277 + 31446739 = 31447016
409 + 31446607 = 31447016

Showing the first eight; more decompositions exist.
