Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672120, here are decompositions:

3 + 8672117 = 8672120
19 + 8672101 = 8672120
73 + 8672047 = 8672120
139 + 8671981 = 8672120
283 + 8671837 = 8672120
409 + 8671711 = 8672120
487 + 8671633 = 8672120
547 + 8671573 = 8672120

Showing the first eight; more decompositions exist.
