Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653572, here are decompositions:

19 + 8653553 = 8653572
23 + 8653549 = 8653572
43 + 8653529 = 8653572
199 + 8653373 = 8653572
211 + 8653361 = 8653572
229 + 8653343 = 8653572
293 + 8653279 = 8653572
311 + 8653261 = 8653572

Showing the first eight; more decompositions exist.
