Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503546, here are decompositions:

17 + 31503529 = 31503546
37 + 31503509 = 31503546
103 + 31503443 = 31503546
167 + 31503379 = 31503546
223 + 31503323 = 31503546
233 + 31503313 = 31503546
317 + 31503229 = 31503546
337 + 31503209 = 31503546

Showing the first eight; more decompositions exist.
