Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752842, here are decompositions:

19 + 8752823 = 8752842
41 + 8752801 = 8752842
61 + 8752781 = 8752842
71 + 8752771 = 8752842
73 + 8752769 = 8752842
101 + 8752741 = 8752842
191 + 8752651 = 8752842
199 + 8752643 = 8752842

Showing the first eight; more decompositions exist.
