Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530110, here are decompositions:

13 + 31530097 = 31530110
67 + 31530043 = 31530110
109 + 31530001 = 31530110
211 + 31529899 = 31530110
229 + 31529881 = 31530110
433 + 31529677 = 31530110
439 + 31529671 = 31530110
487 + 31529623 = 31530110

Showing the first eight; more decompositions exist.
