Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524718, here are decompositions:

41 + 31524677 = 31524718
131 + 31524587 = 31524718
149 + 31524569 = 31524718
461 + 31524257 = 31524718
521 + 31524197 = 31524718
557 + 31524161 = 31524718
1049 + 31523669 = 31524718
1181 + 31523537 = 31524718

Showing the first eight; more decompositions exist.
