Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530598, here are decompositions:

5 + 31530593 = 31530598
101 + 31530497 = 31530598
179 + 31530419 = 31530598
251 + 31530347 = 31530598
257 + 31530341 = 31530598
401 + 31530197 = 31530598
569 + 31530029 = 31530598
881 + 31529717 = 31530598

Showing the first eight; more decompositions exist.
