Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530526, here are decompositions:

3 + 31530523 = 31530526
29 + 31530497 = 31530526
47 + 31530479 = 31530526
89 + 31530437 = 31530526
107 + 31530419 = 31530526
149 + 31530377 = 31530526
179 + 31530347 = 31530526
233 + 31530293 = 31530526

Showing the first eight; more decompositions exist.
