Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524984, here are decompositions:

17 + 31524967 = 31524984
47 + 31524937 = 31524984
191 + 31524793 = 31524984
193 + 31524791 = 31524984
263 + 31524721 = 31524984
307 + 31524677 = 31524984
311 + 31524673 = 31524984
397 + 31524587 = 31524984

Showing the first eight; more decompositions exist.
