Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503936, here are decompositions:

5 + 31503931 = 31503936
7 + 31503929 = 31503936
19 + 31503917 = 31503936
53 + 31503883 = 31503936
73 + 31503863 = 31503936
83 + 31503853 = 31503936
89 + 31503847 = 31503936
127 + 31503809 = 31503936

Showing the first eight; more decompositions exist.
