Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644342, here are decompositions:

11 + 8644331 = 8644342
41 + 8644301 = 8644342
89 + 8644253 = 8644342
251 + 8644091 = 8644342
281 + 8644061 = 8644342
293 + 8644049 = 8644342
383 + 8643959 = 8644342
389 + 8643953 = 8644342

Showing the first eight; more decompositions exist.
