Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503252, here are decompositions:

23 + 31503229 = 31503252
43 + 31503209 = 31503252
71 + 31503181 = 31503252
73 + 31503179 = 31503252
101 + 31503151 = 31503252
113 + 31503139 = 31503252
149 + 31503103 = 31503252
191 + 31503061 = 31503252

Showing the first eight; more decompositions exist.
