Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503410, here are decompositions:

31 + 31503379 = 31503410
67 + 31503343 = 31503410
73 + 31503337 = 31503410
79 + 31503331 = 31503410
97 + 31503313 = 31503410
151 + 31503259 = 31503410
181 + 31503229 = 31503410
193 + 31503217 = 31503410

Showing the first eight; more decompositions exist.
