Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524844, here are decompositions:

5 + 31524839 = 31524844
47 + 31524797 = 31524844
53 + 31524791 = 31524844
167 + 31524677 = 31524844
257 + 31524587 = 31524844
311 + 31524533 = 31524844
587 + 31524257 = 31524844
647 + 31524197 = 31524844

Showing the first eight; more decompositions exist.
