Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687142, here are decompositions:

11 + 8687131 = 8687142
53 + 8687089 = 8687142
73 + 8687069 = 8687142
181 + 8686961 = 8687142
241 + 8686901 = 8687142
313 + 8686829 = 8687142
421 + 8686721 = 8687142
439 + 8686703 = 8687142

Showing the first eight; more decompositions exist.
