Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534318, here are decompositions:

17 + 31534301 = 31534318
47 + 31534271 = 31534318
71 + 31534247 = 31534318
131 + 31534187 = 31534318
149 + 31534169 = 31534318
197 + 31534121 = 31534318
239 + 31534079 = 31534318
251 + 31534067 = 31534318

Showing the first eight; more decompositions exist.
