Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503924, here are decompositions:

7 + 31503917 = 31503924
13 + 31503911 = 31503924
37 + 31503887 = 31503924
41 + 31503883 = 31503924
61 + 31503863 = 31503924
71 + 31503853 = 31503924
83 + 31503841 = 31503924
113 + 31503811 = 31503924

Showing the first eight; more decompositions exist.
