Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530052, here are decompositions:

23 + 31530029 = 31530052
83 + 31529969 = 31530052
233 + 31529819 = 31530052
269 + 31529783 = 31530052
383 + 31529669 = 31530052
401 + 31529651 = 31530052
773 + 31529279 = 31530052
809 + 31529243 = 31530052

Showing the first eight; more decompositions exist.
