Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736520, here are decompositions:

11 + 8736509 = 8736520
17 + 8736503 = 8736520
47 + 8736473 = 8736520
59 + 8736461 = 8736520
71 + 8736449 = 8736520
179 + 8736341 = 8736520
197 + 8736323 = 8736520
257 + 8736263 = 8736520

Showing the first eight; more decompositions exist.
