Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503552, here are decompositions:

23 + 31503529 = 31503552
43 + 31503509 = 31503552
83 + 31503469 = 31503552
109 + 31503443 = 31503552
173 + 31503379 = 31503552
191 + 31503361 = 31503552
211 + 31503341 = 31503552
229 + 31503323 = 31503552

Showing the first eight; more decompositions exist.
