Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673872, here are decompositions:

271 + 8673601 = 8673872
373 + 8673499 = 8673872
409 + 8673463 = 8673872
439 + 8673433 = 8673872
499 + 8673373 = 8673872
601 + 8673271 = 8673872
673 + 8673199 = 8673872
751 + 8673121 = 8673872

Showing the first eight; more decompositions exist.
