Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573452, here are decompositions:

59 + 31573393 = 31573452
61 + 31573391 = 31573452
89 + 31573363 = 31573452
173 + 31573279 = 31573452
191 + 31573261 = 31573452
193 + 31573259 = 31573452
199 + 31573253 = 31573452
241 + 31573211 = 31573452

Showing the first eight; more decompositions exist.
