Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530164, here are decompositions:

67 + 31530097 = 31530164
103 + 31530061 = 31530164
163 + 31530001 = 31530164
241 + 31529923 = 31530164
283 + 31529881 = 31530164
487 + 31529677 = 31530164
541 + 31529623 = 31530164
571 + 31529593 = 31530164

Showing the first eight; more decompositions exist.
