Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31612258, here are decompositions:

17 + 31612241 = 31612258
59 + 31612199 = 31612258
107 + 31612151 = 31612258
137 + 31612121 = 31612258
149 + 31612109 = 31612258
179 + 31612079 = 31612258
317 + 31611941 = 31612258
347 + 31611911 = 31612258

Showing the first eight; more decompositions exist.
