Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503504, here are decompositions:

61 + 31503443 = 31503504
163 + 31503341 = 31503504
167 + 31503337 = 31503504
173 + 31503331 = 31503504
181 + 31503323 = 31503504
191 + 31503313 = 31503504
337 + 31503167 = 31503504
353 + 31503151 = 31503504

Showing the first eight; more decompositions exist.
