Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530476, here are decompositions:

67 + 31530409 = 31530476
127 + 31530349 = 31530476
379 + 31530097 = 31530476
433 + 31530043 = 31530476
499 + 31529977 = 31530476
577 + 31529899 = 31530476
727 + 31529749 = 31530476
853 + 31529623 = 31530476

Showing the first eight; more decompositions exist.
