Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503300, here are decompositions:

41 + 31503259 = 31503300
71 + 31503229 = 31503300
83 + 31503217 = 31503300
97 + 31503203 = 31503300
149 + 31503151 = 31503300
181 + 31503119 = 31503300
193 + 31503107 = 31503300
197 + 31503103 = 31503300

Showing the first eight; more decompositions exist.
