Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662572, here are decompositions:

19 + 8662553 = 8662572
31 + 8662541 = 8662572
41 + 8662531 = 8662572
89 + 8662483 = 8662572
101 + 8662471 = 8662572
131 + 8662441 = 8662572
223 + 8662349 = 8662572
229 + 8662343 = 8662572

Showing the first eight; more decompositions exist.
