Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642252, here are decompositions:

79 + 8642173 = 8642252
193 + 8642059 = 8642252
379 + 8641873 = 8642252
433 + 8641819 = 8642252
601 + 8641651 = 8642252
631 + 8641621 = 8642252
709 + 8641543 = 8642252
733 + 8641519 = 8642252

Showing the first eight; more decompositions exist.
