Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638052, here are decompositions:

13 + 8638039 = 8638052
19 + 8638033 = 8638052
61 + 8637991 = 8638052
79 + 8637973 = 8638052
109 + 8637943 = 8638052
223 + 8637829 = 8638052
433 + 8637619 = 8638052
571 + 8637481 = 8638052

Showing the first eight; more decompositions exist.
