Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723584, here are decompositions:

53 + 8723531 = 8723584
101 + 8723483 = 8723584
197 + 8723387 = 8723584
263 + 8723321 = 8723584
281 + 8723303 = 8723584
461 + 8723123 = 8723584
503 + 8723081 = 8723584
521 + 8723063 = 8723584

Showing the first eight; more decompositions exist.
