Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524148, here are decompositions:

41 + 31524107 = 31524148
101 + 31524047 = 31524148
137 + 31524011 = 31524148
347 + 31523801 = 31524148
479 + 31523669 = 31524148
569 + 31523579 = 31524148
839 + 31523309 = 31524148
881 + 31523267 = 31524148

Showing the first eight; more decompositions exist.
