Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31447922, here are decompositions:

19 + 31447903 = 31447922
109 + 31447813 = 31447922
139 + 31447783 = 31447922
241 + 31447681 = 31447922
349 + 31447573 = 31447922
733 + 31447189 = 31447922
823 + 31447099 = 31447922
853 + 31447069 = 31447922

Showing the first eight; more decompositions exist.
