Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761580, here are decompositions:

43 + 8761537 = 8761580
73 + 8761507 = 8761580
127 + 8761453 = 8761580
151 + 8761429 = 8761580
241 + 8761339 = 8761580
277 + 8761303 = 8761580
283 + 8761297 = 8761580
337 + 8761243 = 8761580

Showing the first eight; more decompositions exist.
