Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503676, here are decompositions:

3 + 31503673 = 31503676
107 + 31503569 = 31503676
167 + 31503509 = 31503676
233 + 31503443 = 31503676
353 + 31503323 = 31503676
467 + 31503209 = 31503676
509 + 31503167 = 31503676
557 + 31503119 = 31503676

Showing the first eight; more decompositions exist.
