Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8752572, here are decompositions:

5 + 8752567 = 8752572
11 + 8752561 = 8752572
19 + 8752553 = 8752572
29 + 8752543 = 8752572
41 + 8752531 = 8752572
61 + 8752511 = 8752572
131 + 8752441 = 8752572
151 + 8752421 = 8752572

Showing the first eight; more decompositions exist.
