Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524970, here are decompositions:

3 + 31524967 = 31524970
107 + 31524863 = 31524970
131 + 31524839 = 31524970
173 + 31524797 = 31524970
179 + 31524791 = 31524970
293 + 31524677 = 31524970
383 + 31524587 = 31524970
401 + 31524569 = 31524970

Showing the first eight; more decompositions exist.
