Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673444, here are decompositions:

11 + 8673433 = 8673444
23 + 8673421 = 8673444
67 + 8673377 = 8673444
71 + 8673373 = 8673444
83 + 8673361 = 8673444
97 + 8673347 = 8673444
103 + 8673341 = 8673444
151 + 8673293 = 8673444

Showing the first eight; more decompositions exist.
