Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725380, here are decompositions:

17 + 8725363 = 8725380
19 + 8725361 = 8725380
23 + 8725357 = 8725380
61 + 8725319 = 8725380
73 + 8725307 = 8725380
101 + 8725279 = 8725380
127 + 8725253 = 8725380
137 + 8725243 = 8725380

Showing the first eight; more decompositions exist.
