Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752578, here are decompositions:

5 + 8752573 = 8752578
11 + 8752567 = 8752578
17 + 8752561 = 8752578
41 + 8752537 = 8752578
47 + 8752531 = 8752578
67 + 8752511 = 8752578
71 + 8752507 = 8752578
101 + 8752477 = 8752578

Showing the first eight; more decompositions exist.
