Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747256, here are decompositions:

5 + 8747251 = 8747256
13 + 8747243 = 8747256
43 + 8747213 = 8747256
97 + 8747159 = 8747256
137 + 8747119 = 8747256
163 + 8747093 = 8747256
173 + 8747083 = 8747256
257 + 8746999 = 8747256

Showing the first eight; more decompositions exist.
