Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480170, here are decompositions:

41 + 31480129 = 31480170
53 + 31480117 = 31480170
67 + 31480103 = 31480170
79 + 31480091 = 31480170
109 + 31480061 = 31480170
149 + 31480021 = 31480170
151 + 31480019 = 31480170
223 + 31479947 = 31480170

Showing the first eight; more decompositions exist.
