Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524394, here are decompositions:

101 + 31524293 = 31524394
137 + 31524257 = 31524394
197 + 31524197 = 31524394
227 + 31524167 = 31524394
233 + 31524161 = 31524394
347 + 31524047 = 31524394
383 + 31524011 = 31524394
593 + 31523801 = 31524394

Showing the first eight; more decompositions exist.
