Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617948, here are decompositions:

5 + 8617943 = 8617948
71 + 8617877 = 8617948
149 + 8617799 = 8617948
179 + 8617769 = 8617948
401 + 8617547 = 8617948
509 + 8617439 = 8617948
557 + 8617391 = 8617948
587 + 8617361 = 8617948

Showing the first eight; more decompositions exist.
