Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673520, here are decompositions:

3 + 8673517 = 8673520
101 + 8673419 = 8673520
131 + 8673389 = 8673520
173 + 8673347 = 8673520
179 + 8673341 = 8673520
227 + 8673293 = 8673520
311 + 8673209 = 8673520
353 + 8673167 = 8673520

Showing the first eight; more decompositions exist.
