Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621456, here are decompositions:

3 + 8621453 = 8621456
13 + 8621443 = 8621456
43 + 8621413 = 8621456
79 + 8621377 = 8621456
157 + 8621299 = 8621456
313 + 8621143 = 8621456
367 + 8621089 = 8621456
373 + 8621083 = 8621456

Showing the first eight; more decompositions exist.
