Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503904, here are decompositions:

17 + 31503887 = 31503904
41 + 31503863 = 31503904
191 + 31503713 = 31503904
347 + 31503557 = 31503904
461 + 31503443 = 31503904
563 + 31503341 = 31503904
701 + 31503203 = 31503904
797 + 31503107 = 31503904

Showing the first eight; more decompositions exist.
