Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736580, here are decompositions:

71 + 8736509 = 8736580
107 + 8736473 = 8736580
131 + 8736449 = 8736580
179 + 8736401 = 8736580
239 + 8736341 = 8736580
257 + 8736323 = 8736580
317 + 8736263 = 8736580
389 + 8736191 = 8736580

Showing the first eight; more decompositions exist.
