Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747872, here are decompositions:

41 + 8747831 = 8747872
53 + 8747819 = 8747872
83 + 8747789 = 8747872
113 + 8747759 = 8747872
149 + 8747723 = 8747872
269 + 8747603 = 8747872
293 + 8747579 = 8747872
311 + 8747561 = 8747872

Showing the first eight; more decompositions exist.
