Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573486, here are decompositions:

23 + 31573463 = 31573486
59 + 31573427 = 31573486
227 + 31573259 = 31573486
233 + 31573253 = 31573486
353 + 31573133 = 31573486
359 + 31573127 = 31573486
383 + 31573103 = 31573486
449 + 31573037 = 31573486

Showing the first eight; more decompositions exist.
