Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747436, here are decompositions:

13 + 8747423 = 8747436
17 + 8747419 = 8747436
29 + 8747407 = 8747436
107 + 8747329 = 8747436
109 + 8747327 = 8747436
163 + 8747273 = 8747436
179 + 8747257 = 8747436
193 + 8747243 = 8747436

Showing the first eight; more decompositions exist.
