Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747956, here are decompositions:

23 + 8747933 = 8747956
29 + 8747927 = 8747956
53 + 8747903 = 8747956
137 + 8747819 = 8747956
149 + 8747807 = 8747956
167 + 8747789 = 8747956
179 + 8747777 = 8747956
197 + 8747759 = 8747956

Showing the first eight; more decompositions exist.
