Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534170, here are decompositions:

29 + 31534141 = 31534170
53 + 31534117 = 31534170
67 + 31534103 = 31534170
97 + 31534073 = 31534170
103 + 31534067 = 31534170
113 + 31534057 = 31534170
137 + 31534033 = 31534170
191 + 31533979 = 31534170

Showing the first eight; more decompositions exist.
