Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747466, here are decompositions:

43 + 8747423 = 8747466
47 + 8747419 = 8747466
59 + 8747407 = 8747466
137 + 8747329 = 8747466
139 + 8747327 = 8747466
193 + 8747273 = 8747466
223 + 8747243 = 8747466
307 + 8747159 = 8747466

Showing the first eight; more decompositions exist.
