Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503282, here are decompositions:

23 + 31503259 = 31503282
53 + 31503229 = 31503282
73 + 31503209 = 31503282
79 + 31503203 = 31503282
101 + 31503181 = 31503282
103 + 31503179 = 31503282
131 + 31503151 = 31503282
163 + 31503119 = 31503282

Showing the first eight; more decompositions exist.
