Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643004, here are decompositions:

53 + 8642951 = 8643004
101 + 8642903 = 8643004
107 + 8642897 = 8643004
257 + 8642747 = 8643004
281 + 8642723 = 8643004
353 + 8642651 = 8643004
701 + 8642303 = 8643004
857 + 8642147 = 8643004

Showing the first eight; more decompositions exist.
