Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503348, here are decompositions:

5 + 31503343 = 31503348
7 + 31503341 = 31503348
11 + 31503337 = 31503348
17 + 31503331 = 31503348
89 + 31503259 = 31503348
131 + 31503217 = 31503348
139 + 31503209 = 31503348
167 + 31503181 = 31503348

Showing the first eight; more decompositions exist.
