Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8628344, here are decompositions:

73 + 8628271 = 8628344
157 + 8628187 = 8628344
163 + 8628181 = 8628344
223 + 8628121 = 8628344
313 + 8628031 = 8628344
337 + 8628007 = 8628344
367 + 8627977 = 8628344
397 + 8627947 = 8628344

Showing the first eight; more decompositions exist.
