Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736540, here are decompositions:

11 + 8736529 = 8736540
31 + 8736509 = 8736540
37 + 8736503 = 8736540
67 + 8736473 = 8736540
79 + 8736461 = 8736540
107 + 8736433 = 8736540
139 + 8736401 = 8736540
173 + 8736367 = 8736540

Showing the first eight; more decompositions exist.
