Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527924, here are decompositions:

11 + 31527913 = 31527924
37 + 31527887 = 31527924
97 + 31527827 = 31527924
107 + 31527817 = 31527924
137 + 31527787 = 31527924
223 + 31527701 = 31527924
227 + 31527697 = 31527924
347 + 31527577 = 31527924

Showing the first eight; more decompositions exist.
