Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752782, here are decompositions:

11 + 8752771 = 8752782
13 + 8752769 = 8752782
41 + 8752741 = 8752782
131 + 8752651 = 8752782
139 + 8752643 = 8752782
163 + 8752619 = 8752782
229 + 8752553 = 8752782
239 + 8752543 = 8752782

Showing the first eight; more decompositions exist.
