Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31484160, here are decompositions:

17 + 31484143 = 31484160
31 + 31484129 = 31484160
67 + 31484093 = 31484160
79 + 31484081 = 31484160
89 + 31484071 = 31484160
101 + 31484059 = 31484160
179 + 31483981 = 31484160
181 + 31483979 = 31484160

Showing the first eight; more decompositions exist.
