Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530334, here are decompositions:

23 + 31530311 = 31530334
41 + 31530293 = 31530334
131 + 31530203 = 31530334
137 + 31530197 = 31530334
191 + 31530143 = 31530334
317 + 31530017 = 31530334
401 + 31529933 = 31530334
443 + 31529891 = 31530334

Showing the first eight; more decompositions exist.
