Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475924, here are decompositions:

13 + 31475911 = 31475924
97 + 31475827 = 31475924
127 + 31475797 = 31475924
211 + 31475713 = 31475924
241 + 31475683 = 31475924
313 + 31475611 = 31475924
433 + 31475491 = 31475924
523 + 31475401 = 31475924

Showing the first eight; more decompositions exist.
