Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524556, here are decompositions:

23 + 31524533 = 31524556
47 + 31524509 = 31524556
137 + 31524419 = 31524556
263 + 31524293 = 31524556
359 + 31524197 = 31524556
389 + 31524167 = 31524556
449 + 31524107 = 31524556
509 + 31524047 = 31524556

Showing the first eight; more decompositions exist.
