Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747806, here are decompositions:

3 + 8747803 = 8747806
17 + 8747789 = 8747806
29 + 8747777 = 8747806
47 + 8747759 = 8747806
59 + 8747747 = 8747806
83 + 8747723 = 8747806
227 + 8747579 = 8747806
233 + 8747573 = 8747806

Showing the first eight; more decompositions exist.
