Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747518, here are decompositions:

5 + 8747513 = 8747518
29 + 8747489 = 8747518
47 + 8747471 = 8747518
137 + 8747381 = 8747518
191 + 8747327 = 8747518
257 + 8747261 = 8747518
347 + 8747171 = 8747518
359 + 8747159 = 8747518

Showing the first eight; more decompositions exist.
