Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761584, here are decompositions:

37 + 8761547 = 8761584
47 + 8761537 = 8761584
53 + 8761531 = 8761584
67 + 8761517 = 8761584
127 + 8761457 = 8761584
131 + 8761453 = 8761584
151 + 8761433 = 8761584
257 + 8761327 = 8761584

Showing the first eight; more decompositions exist.
