Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524190, here are decompositions:

23 + 31524167 = 31524190
29 + 31524161 = 31524190
83 + 31524107 = 31524190
167 + 31524023 = 31524190
179 + 31524011 = 31524190
251 + 31523939 = 31524190
389 + 31523801 = 31524190
521 + 31523669 = 31524190

Showing the first eight; more decompositions exist.
