Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673572, here are decompositions:

3 + 8673569 = 8673572
73 + 8673499 = 8673572
109 + 8673463 = 8673572
139 + 8673433 = 8673572
151 + 8673421 = 8673572
199 + 8673373 = 8673572
211 + 8673361 = 8673572
373 + 8673199 = 8673572

Showing the first eight; more decompositions exist.
