Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503876, here are decompositions:

13 + 31503863 = 31503876
23 + 31503853 = 31503876
29 + 31503847 = 31503876
67 + 31503809 = 31503876
97 + 31503779 = 31503876
127 + 31503749 = 31503876
149 + 31503727 = 31503876
163 + 31503713 = 31503876

Showing the first eight; more decompositions exist.
