Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747800, here are decompositions:

11 + 8747789 = 8747800
23 + 8747777 = 8747800
41 + 8747759 = 8747800
53 + 8747747 = 8747800
197 + 8747603 = 8747800
227 + 8747573 = 8747800
239 + 8747561 = 8747800
311 + 8747489 = 8747800

Showing the first eight; more decompositions exist.
