Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687044, here are decompositions:

17 + 8687027 = 8687044
83 + 8686961 = 8687044
167 + 8686877 = 8687044
383 + 8686661 = 8687044
557 + 8686487 = 8687044
647 + 8686397 = 8687044
683 + 8686361 = 8687044
857 + 8686187 = 8687044

Showing the first eight; more decompositions exist.
