Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534258, here are decompositions:

11 + 31534247 = 31534258
17 + 31534241 = 31534258
59 + 31534199 = 31534258
71 + 31534187 = 31534258
89 + 31534169 = 31534258
137 + 31534121 = 31534258
179 + 31534079 = 31534258
191 + 31534067 = 31534258

Showing the first eight; more decompositions exist.
