Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748564, here are decompositions:

61 + 8748503 = 8748564
101 + 8748463 = 8748564
151 + 8748413 = 8748564
197 + 8748367 = 8748564
233 + 8748331 = 8748564
241 + 8748323 = 8748564
277 + 8748287 = 8748564
283 + 8748281 = 8748564

Showing the first eight; more decompositions exist.
