Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573504, here are decompositions:

3 + 31573501 = 31573504
5 + 31573499 = 31573504
41 + 31573463 = 31573504
113 + 31573391 = 31573504
227 + 31573277 = 31573504
251 + 31573253 = 31573504
293 + 31573211 = 31573504
353 + 31573151 = 31573504

Showing the first eight; more decompositions exist.
