Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524056, here are decompositions:

7 + 31524049 = 31524056
13 + 31524043 = 31524056
43 + 31524013 = 31524056
103 + 31523953 = 31524056
139 + 31523917 = 31524056
307 + 31523749 = 31524056
349 + 31523707 = 31524056
397 + 31523659 = 31524056

Showing the first eight; more decompositions exist.
