Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687402, here are decompositions:

19 + 8687383 = 8687402
43 + 8687359 = 8687402
103 + 8687299 = 8687402
193 + 8687209 = 8687402
271 + 8687131 = 8687402
313 + 8687089 = 8687402
421 + 8686981 = 8687402
673 + 8686729 = 8687402

Showing the first eight; more decompositions exist.
