Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573410, here are decompositions:

17 + 31573393 = 31573410
19 + 31573391 = 31573410
47 + 31573363 = 31573410
53 + 31573357 = 31573410
131 + 31573279 = 31573410
149 + 31573261 = 31573410
151 + 31573259 = 31573410
157 + 31573253 = 31573410

Showing the first eight; more decompositions exist.
