Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761478, here are decompositions:

139 + 8761339 = 8761478
151 + 8761327 = 8761478
181 + 8761297 = 8761478
199 + 8761279 = 8761478
241 + 8761237 = 8761478
337 + 8761141 = 8761478
379 + 8761099 = 8761478
487 + 8760991 = 8761478

Showing the first eight; more decompositions exist.
