Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638010, here are decompositions:

19 + 8637991 = 8638010
37 + 8637973 = 8638010
67 + 8637943 = 8638010
163 + 8637847 = 8638010
181 + 8637829 = 8638010
223 + 8637787 = 8638010
313 + 8637697 = 8638010
373 + 8637637 = 8638010

Showing the first eight; more decompositions exist.
