Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687132, here are decompositions:

43 + 8687089 = 8687132
151 + 8686981 = 8687132
463 + 8686669 = 8687132
631 + 8686501 = 8687132
661 + 8686471 = 8687132
673 + 8686459 = 8687132
823 + 8686309 = 8687132
859 + 8686273 = 8687132

Showing the first eight; more decompositions exist.
