Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31500274, here are decompositions:

11 + 31500263 = 31500274
53 + 31500221 = 31500274
167 + 31500107 = 31500274
173 + 31500101 = 31500274
191 + 31500083 = 31500274
227 + 31500047 = 31500274
251 + 31500023 = 31500274
257 + 31500017 = 31500274

Showing the first eight; more decompositions exist.
