Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747922, here are decompositions:

5 + 8747917 = 8747922
19 + 8747903 = 8747922
31 + 8747891 = 8747922
59 + 8747863 = 8747922
103 + 8747819 = 8747922
163 + 8747759 = 8747922
179 + 8747743 = 8747922
199 + 8747723 = 8747922

Showing the first eight; more decompositions exist.
