Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541298, here are decompositions:

17 + 31541281 = 31541298
29 + 31541269 = 31541298
31 + 31541267 = 31541298
137 + 31541161 = 31541298
157 + 31541141 = 31541298
181 + 31541117 = 31541298
197 + 31541101 = 31541298
227 + 31541071 = 31541298

Showing the first eight; more decompositions exist.
