Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573534, here are decompositions:

11 + 31573523 = 31573534
71 + 31573463 = 31573534
107 + 31573427 = 31573534
173 + 31573361 = 31573534
257 + 31573277 = 31573534
281 + 31573253 = 31573534
383 + 31573151 = 31573534
401 + 31573133 = 31573534

Showing the first eight; more decompositions exist.
