Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654780, here are decompositions:

7 + 8654773 = 8654780
19 + 8654761 = 8654780
31 + 8654749 = 8654780
67 + 8654713 = 8654780
139 + 8654641 = 8654780
163 + 8654617 = 8654780
313 + 8654467 = 8654780
349 + 8654431 = 8654780

Showing the first eight; more decompositions exist.
