Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747644, here are decompositions:

41 + 8747603 = 8747644
71 + 8747573 = 8747644
83 + 8747561 = 8747644
131 + 8747513 = 8747644
173 + 8747471 = 8747644
263 + 8747381 = 8747644
317 + 8747327 = 8747644
383 + 8747261 = 8747644

Showing the first eight; more decompositions exist.
