Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524566, here are decompositions:

43 + 31524523 = 31524566
67 + 31524499 = 31524566
97 + 31524469 = 31524566
163 + 31524403 = 31524566
223 + 31524343 = 31524566
373 + 31524193 = 31524566
433 + 31524133 = 31524566
523 + 31524043 = 31524566

Showing the first eight; more decompositions exist.
