Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503346, here are decompositions:

3 + 31503343 = 31503346
5 + 31503341 = 31503346
23 + 31503323 = 31503346
137 + 31503209 = 31503346
167 + 31503179 = 31503346
179 + 31503167 = 31503346
227 + 31503119 = 31503346
239 + 31503107 = 31503346

Showing the first eight; more decompositions exist.
