Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501794, here are decompositions:

13 + 31501781 = 31501794
43 + 31501751 = 31501794
53 + 31501741 = 31501794
67 + 31501727 = 31501794
73 + 31501721 = 31501794
173 + 31501621 = 31501794
211 + 31501583 = 31501794
227 + 31501567 = 31501794

Showing the first eight; more decompositions exist.
