Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673920, here are decompositions:

7 + 8673913 = 8673920
19 + 8673901 = 8673920
43 + 8673877 = 8673920
103 + 8673817 = 8673920
139 + 8673781 = 8673920
193 + 8673727 = 8673920
349 + 8673571 = 8673920
373 + 8673547 = 8673920

Showing the first eight; more decompositions exist.
