Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503270, here are decompositions:

11 + 31503259 = 31503270
41 + 31503229 = 31503270
53 + 31503217 = 31503270
61 + 31503209 = 31503270
67 + 31503203 = 31503270
89 + 31503181 = 31503270
103 + 31503167 = 31503270
131 + 31503139 = 31503270

Showing the first eight; more decompositions exist.
