Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31503326, here are decompositions:

3 + 31503323 = 31503326
13 + 31503313 = 31503326
67 + 31503259 = 31503326
97 + 31503229 = 31503326
109 + 31503217 = 31503326
223 + 31503103 = 31503326
367 + 31502959 = 31503326
373 + 31502953 = 31503326

Showing the first eight; more decompositions exist.
