Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644438, here are decompositions:

41 + 8644397 = 8644438
107 + 8644331 = 8644438
137 + 8644301 = 8644438
251 + 8644187 = 8644438
281 + 8644157 = 8644438
347 + 8644091 = 8644438
389 + 8644049 = 8644438
419 + 8644019 = 8644438

Showing the first eight; more decompositions exist.
