Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687038, here are decompositions:

11 + 8687027 = 8687038
137 + 8686901 = 8687038
149 + 8686889 = 8687038
197 + 8686841 = 8687038
317 + 8686721 = 8687038
359 + 8686679 = 8687038
449 + 8686589 = 8687038
509 + 8686529 = 8687038

Showing the first eight; more decompositions exist.
