Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538096, here are decompositions:

43 + 31538053 = 31538096
67 + 31538029 = 31538096
97 + 31537999 = 31538096
157 + 31537939 = 31538096
193 + 31537903 = 31538096
349 + 31537747 = 31538096
379 + 31537717 = 31538096
409 + 31537687 = 31538096

Showing the first eight; more decompositions exist.
