Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530234, here are decompositions:

23 + 31530211 = 31530234
31 + 31530203 = 31530234
37 + 31530197 = 31530234
53 + 31530181 = 31530234
61 + 31530173 = 31530234
137 + 31530097 = 31530234
173 + 31530061 = 31530234
191 + 31530043 = 31530234

Showing the first eight; more decompositions exist.
