Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671552, here are decompositions:

3 + 8671549 = 8671552
41 + 8671511 = 8671552
53 + 8671499 = 8671552
83 + 8671469 = 8671552
89 + 8671463 = 8671552
191 + 8671361 = 8671552
359 + 8671193 = 8671552
401 + 8671151 = 8671552

Showing the first eight; more decompositions exist.
