Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503016, here are decompositions:

23 + 31502993 = 31503016
53 + 31502963 = 31503016
89 + 31502927 = 31503016
239 + 31502777 = 31503016
317 + 31502699 = 31503016
557 + 31502459 = 31503016
653 + 31502363 = 31503016
683 + 31502333 = 31503016

Showing the first eight; more decompositions exist.
