Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8727930, here are decompositions:

17 + 8727913 = 8727930
23 + 8727907 = 8727930
31 + 8727899 = 8727930
59 + 8727871 = 8727930
73 + 8727857 = 8727930
139 + 8727791 = 8727930
151 + 8727779 = 8727930
157 + 8727773 = 8727930

Showing the first eight; more decompositions exist.
