Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8645444, here are decompositions:

13 + 8645431 = 8645444
37 + 8645407 = 8645444
103 + 8645341 = 8645444
151 + 8645293 = 8645444
163 + 8645281 = 8645444
331 + 8645113 = 8645444
373 + 8645071 = 8645444
397 + 8645047 = 8645444

Showing the first eight; more decompositions exist.
