Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8591930, here are decompositions:

3 + 8591927 = 8591930
31 + 8591899 = 8591930
43 + 8591887 = 8591930
103 + 8591827 = 8591930
157 + 8591773 = 8591930
241 + 8591689 = 8591930
307 + 8591623 = 8591930
313 + 8591617 = 8591930

Showing the first eight; more decompositions exist.
