Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524804, here are decompositions:

7 + 31524797 = 31524804
11 + 31524793 = 31524804
13 + 31524791 = 31524804
37 + 31524767 = 31524804
41 + 31524763 = 31524804
83 + 31524721 = 31524804
127 + 31524677 = 31524804
131 + 31524673 = 31524804

Showing the first eight; more decompositions exist.
