Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534164, here are decompositions:

23 + 31534141 = 31534164
43 + 31534121 = 31534164
47 + 31534117 = 31534164
61 + 31534103 = 31534164
97 + 31534067 = 31534164
107 + 31534057 = 31534164
113 + 31534051 = 31534164
131 + 31534033 = 31534164

Showing the first eight; more decompositions exist.
