Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503696, here are decompositions:

23 + 31503673 = 31503696
53 + 31503643 = 31503696
127 + 31503569 = 31503696
137 + 31503559 = 31503696
139 + 31503557 = 31503696
167 + 31503529 = 31503696
227 + 31503469 = 31503696
317 + 31503379 = 31503696

Showing the first eight; more decompositions exist.
