Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503196, here are decompositions:

17 + 31503179 = 31503196
29 + 31503167 = 31503196
89 + 31503107 = 31503196
233 + 31502963 = 31503196
269 + 31502927 = 31503196
419 + 31502777 = 31503196
509 + 31502687 = 31503196
863 + 31502333 = 31503196

Showing the first eight; more decompositions exist.
