Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530688, here are decompositions:

5 + 31530683 = 31530688
29 + 31530659 = 31530688
47 + 31530641 = 31530688
71 + 31530617 = 31530688
191 + 31530497 = 31530688
251 + 31530437 = 31530688
269 + 31530419 = 31530688
311 + 31530377 = 31530688

Showing the first eight; more decompositions exist.
