Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8761800, here are decompositions:

11 + 8761789 = 8761800
37 + 8761763 = 8761800
67 + 8761733 = 8761800
79 + 8761721 = 8761800
97 + 8761703 = 8761800
109 + 8761691 = 8761800
167 + 8761633 = 8761800
181 + 8761619 = 8761800

Showing the first eight; more decompositions exist.
