Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503344, here are decompositions:

3 + 31503341 = 31503344
7 + 31503337 = 31503344
13 + 31503331 = 31503344
31 + 31503313 = 31503344
127 + 31503217 = 31503344
163 + 31503181 = 31503344
193 + 31503151 = 31503344
241 + 31503103 = 31503344

Showing the first eight; more decompositions exist.
