Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637938, here are decompositions:

109 + 8637829 = 8637938
151 + 8637787 = 8637938
241 + 8637697 = 8637938
271 + 8637667 = 8637938
457 + 8637481 = 8637938
487 + 8637451 = 8637938
601 + 8637337 = 8637938
619 + 8637319 = 8637938

Showing the first eight; more decompositions exist.
