Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677428, here are decompositions:

29 + 8677399 = 8677428
31 + 8677397 = 8677428
37 + 8677391 = 8677428
41 + 8677387 = 8677428
61 + 8677367 = 8677428
131 + 8677297 = 8677428
139 + 8677289 = 8677428
167 + 8677261 = 8677428

Showing the first eight; more decompositions exist.
