Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503392, here are decompositions:

13 + 31503379 = 31503392
31 + 31503361 = 31503392
61 + 31503331 = 31503392
79 + 31503313 = 31503392
163 + 31503229 = 31503392
211 + 31503181 = 31503392
241 + 31503151 = 31503392
331 + 31503061 = 31503392

Showing the first eight; more decompositions exist.
