Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524370, here are decompositions:

113 + 31524257 = 31524370
173 + 31524197 = 31524370
263 + 31524107 = 31524370
347 + 31524023 = 31524370
359 + 31524011 = 31524370
431 + 31523939 = 31524370
569 + 31523801 = 31524370
617 + 31523753 = 31524370

Showing the first eight; more decompositions exist.
