Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471922, here are decompositions:

73 + 31471849 = 31471922
211 + 31471711 = 31471922
241 + 31471681 = 31471922
283 + 31471639 = 31471922
331 + 31471591 = 31471922
373 + 31471549 = 31471922
709 + 31471213 = 31471922
751 + 31471171 = 31471922

Showing the first eight; more decompositions exist.
