Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503718, here are decompositions:

5 + 31503713 = 31503718
149 + 31503569 = 31503718
509 + 31503209 = 31503718
599 + 31503119 = 31503718
821 + 31502897 = 31503718
941 + 31502777 = 31503718
1019 + 31502699 = 31503718
1031 + 31502687 = 31503718

Showing the first eight; more decompositions exist.
