Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644374, here are decompositions:

43 + 8644331 = 8644374
47 + 8644327 = 8644374
73 + 8644301 = 8644374
113 + 8644261 = 8644374
131 + 8644243 = 8644374
227 + 8644147 = 8644374
251 + 8644123 = 8644374
283 + 8644091 = 8644374

Showing the first eight; more decompositions exist.
