Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530628, here are decompositions:

11 + 31530617 = 31530628
131 + 31530497 = 31530628
149 + 31530479 = 31530628
191 + 31530437 = 31530628
251 + 31530377 = 31530628
281 + 31530347 = 31530628
317 + 31530311 = 31530628
359 + 31530269 = 31530628

Showing the first eight; more decompositions exist.
