Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644300, here are decompositions:

47 + 8644253 = 8644300
113 + 8644187 = 8644300
239 + 8644061 = 8644300
251 + 8644049 = 8644300
281 + 8644019 = 8644300
347 + 8643953 = 8644300
359 + 8643941 = 8644300
449 + 8643851 = 8644300

Showing the first eight; more decompositions exist.
