Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544916, here are decompositions:

17 + 31544899 = 31544916
37 + 31544879 = 31544916
59 + 31544857 = 31544916
89 + 31544827 = 31544916
97 + 31544819 = 31544916
157 + 31544759 = 31544916
167 + 31544749 = 31544916
197 + 31544719 = 31544916

Showing the first eight; more decompositions exist.
