Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524026, here are decompositions:

3 + 31524023 = 31524026
13 + 31524013 = 31524026
73 + 31523953 = 31524026
109 + 31523917 = 31524026
223 + 31523803 = 31524026
277 + 31523749 = 31524026
367 + 31523659 = 31524026
379 + 31523647 = 31524026

Showing the first eight; more decompositions exist.
