Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677660, here are decompositions:

53 + 8677607 = 8677660
83 + 8677577 = 8677660
107 + 8677553 = 8677660
149 + 8677511 = 8677660
179 + 8677481 = 8677660
263 + 8677397 = 8677660
269 + 8677391 = 8677660
293 + 8677367 = 8677660

Showing the first eight; more decompositions exist.
