Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761520, here are decompositions:

3 + 8761517 = 8761520
13 + 8761507 = 8761520
67 + 8761453 = 8761520
181 + 8761339 = 8761520
193 + 8761327 = 8761520
223 + 8761297 = 8761520
241 + 8761279 = 8761520
277 + 8761243 = 8761520

Showing the first eight; more decompositions exist.
