Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638852, here are decompositions:

3 + 8638849 = 8638852
191 + 8638661 = 8638852
269 + 8638583 = 8638852
389 + 8638463 = 8638852
401 + 8638451 = 8638852
449 + 8638403 = 8638852
479 + 8638373 = 8638852
503 + 8638349 = 8638852

Showing the first eight; more decompositions exist.
