Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640606, here are decompositions:

5 + 8640601 = 8640606
19 + 8640587 = 8640606
47 + 8640559 = 8640606
53 + 8640553 = 8640606
59 + 8640547 = 8640606
103 + 8640503 = 8640606
113 + 8640493 = 8640606
167 + 8640439 = 8640606

Showing the first eight; more decompositions exist.
