Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747824, here are decompositions:

5 + 8747819 = 8747824
17 + 8747807 = 8747824
47 + 8747777 = 8747824
101 + 8747723 = 8747824
251 + 8747573 = 8747824
263 + 8747561 = 8747824
311 + 8747513 = 8747824
353 + 8747471 = 8747824

Showing the first eight; more decompositions exist.
