Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747986, here are decompositions:

29 + 8747957 = 8747986
53 + 8747933 = 8747986
59 + 8747927 = 8747986
83 + 8747903 = 8747986
167 + 8747819 = 8747986
179 + 8747807 = 8747986
197 + 8747789 = 8747986
227 + 8747759 = 8747986

Showing the first eight; more decompositions exist.
