Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573498, here are decompositions:

71 + 31573427 = 31573498
107 + 31573391 = 31573498
137 + 31573361 = 31573498
239 + 31573259 = 31573498
347 + 31573151 = 31573498
389 + 31573109 = 31573498
461 + 31573037 = 31573498
491 + 31573007 = 31573498

Showing the first eight; more decompositions exist.
