Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761388, here are decompositions:

61 + 8761327 = 8761388
109 + 8761279 = 8761388
151 + 8761237 = 8761388
211 + 8761177 = 8761388
271 + 8761117 = 8761388
379 + 8761009 = 8761388
397 + 8760991 = 8761388
487 + 8760901 = 8761388

Showing the first eight; more decompositions exist.
