Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761778, here are decompositions:

139 + 8761639 = 8761778
241 + 8761537 = 8761778
271 + 8761507 = 8761778
349 + 8761429 = 8761778
439 + 8761339 = 8761778
499 + 8761279 = 8761778
541 + 8761237 = 8761778
601 + 8761177 = 8761778

Showing the first eight; more decompositions exist.
