Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524580, here are decompositions:

11 + 31524569 = 31524580
47 + 31524533 = 31524580
71 + 31524509 = 31524580
383 + 31524197 = 31524580
419 + 31524161 = 31524580
557 + 31524023 = 31524580
569 + 31524011 = 31524580
641 + 31523939 = 31524580

Showing the first eight; more decompositions exist.
