Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637860, here are decompositions:

13 + 8637847 = 8637860
31 + 8637829 = 8637860
73 + 8637787 = 8637860
163 + 8637697 = 8637860
193 + 8637667 = 8637860
223 + 8637637 = 8637860
241 + 8637619 = 8637860
337 + 8637523 = 8637860

Showing the first eight; more decompositions exist.
