Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530084, here are decompositions:

23 + 31530061 = 31530084
41 + 31530043 = 31530084
67 + 31530017 = 31530084
83 + 31530001 = 31530084
107 + 31529977 = 31530084
151 + 31529933 = 31530084
193 + 31529891 = 31530084
241 + 31529843 = 31530084

Showing the first eight; more decompositions exist.
