Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574298, here are decompositions:

37 + 31574261 = 31574298
97 + 31574201 = 31574298
167 + 31574131 = 31574298
191 + 31574107 = 31574298
199 + 31574099 = 31574298
227 + 31574071 = 31574298
251 + 31574047 = 31574298
257 + 31574041 = 31574298

Showing the first eight; more decompositions exist.
