Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530232, here are decompositions:

29 + 31530203 = 31530232
59 + 31530173 = 31530232
89 + 31530143 = 31530232
263 + 31529969 = 31530232
389 + 31529843 = 31530232
449 + 31529783 = 31530232
563 + 31529669 = 31530232
761 + 31529471 = 31530232

Showing the first eight; more decompositions exist.
