Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673860, here are decompositions:

43 + 8673817 = 8673860
79 + 8673781 = 8673860
157 + 8673703 = 8673860
313 + 8673547 = 8673860
397 + 8673463 = 8673860
439 + 8673421 = 8673860
487 + 8673373 = 8673860
499 + 8673361 = 8673860

Showing the first eight; more decompositions exist.
