Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573468, here are decompositions:

5 + 31573463 = 31573468
41 + 31573427 = 31573468
107 + 31573361 = 31573468
191 + 31573277 = 31573468
257 + 31573211 = 31573468
317 + 31573151 = 31573468
359 + 31573109 = 31573468
431 + 31573037 = 31573468

Showing the first eight; more decompositions exist.
