Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673928, here are decompositions:

5 + 8673923 = 8673928
17 + 8673911 = 8673928
89 + 8673839 = 8673928
167 + 8673761 = 8673928
251 + 8673677 = 8673928
317 + 8673611 = 8673928
359 + 8673569 = 8673928
509 + 8673419 = 8673928

Showing the first eight; more decompositions exist.
