Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524628, here are decompositions:

41 + 31524587 = 31524628
59 + 31524569 = 31524628
431 + 31524197 = 31524628
461 + 31524167 = 31524628
467 + 31524161 = 31524628
521 + 31524107 = 31524628
617 + 31524011 = 31524628
827 + 31523801 = 31524628

Showing the first eight; more decompositions exist.
