Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524406, here are decompositions:

3 + 31524403 = 31524406
113 + 31524293 = 31524406
149 + 31524257 = 31524406
239 + 31524167 = 31524406
359 + 31524047 = 31524406
383 + 31524023 = 31524406
467 + 31523939 = 31524406
653 + 31523753 = 31524406

Showing the first eight; more decompositions exist.
