Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528094, here are decompositions:

97 + 31527997 = 31528094
127 + 31527967 = 31528094
163 + 31527931 = 31528094
181 + 31527913 = 31528094
277 + 31527817 = 31528094
307 + 31527787 = 31528094
313 + 31527781 = 31528094
397 + 31527697 = 31528094

Showing the first eight; more decompositions exist.
