Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470896, here are decompositions:

7 + 31470889 = 31470896
43 + 31470853 = 31470896
73 + 31470823 = 31470896
97 + 31470799 = 31470896
103 + 31470793 = 31470896
109 + 31470787 = 31470896
277 + 31470619 = 31470896
349 + 31470547 = 31470896

Showing the first eight; more decompositions exist.
