Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479924, here are decompositions:

43 + 31479881 = 31479924
67 + 31479857 = 31479924
103 + 31479821 = 31479924
107 + 31479817 = 31479924
131 + 31479793 = 31479924
167 + 31479757 = 31479924
181 + 31479743 = 31479924
227 + 31479697 = 31479924

Showing the first eight; more decompositions exist.
