Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503228, here are decompositions:

11 + 31503217 = 31503228
19 + 31503209 = 31503228
47 + 31503181 = 31503228
61 + 31503167 = 31503228
89 + 31503139 = 31503228
109 + 31503119 = 31503228
167 + 31503061 = 31503228
269 + 31502959 = 31503228

Showing the first eight; more decompositions exist.
