Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503882, here are decompositions:

19 + 31503863 = 31503882
29 + 31503853 = 31503882
41 + 31503841 = 31503882
71 + 31503811 = 31503882
73 + 31503809 = 31503882
83 + 31503799 = 31503882
103 + 31503779 = 31503882
131 + 31503751 = 31503882

Showing the first eight; more decompositions exist.
