Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671562, here are decompositions:

13 + 8671549 = 8671562
43 + 8671519 = 8671562
61 + 8671501 = 8671562
181 + 8671381 = 8671562
199 + 8671363 = 8671562
223 + 8671339 = 8671562
241 + 8671321 = 8671562
271 + 8671291 = 8671562

Showing the first eight; more decompositions exist.
