Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737938, here are decompositions:

5 + 8737933 = 8737938
17 + 8737921 = 8737938
67 + 8737871 = 8737938
71 + 8737867 = 8737938
89 + 8737849 = 8737938
109 + 8737829 = 8737938
137 + 8737801 = 8737938
149 + 8737789 = 8737938

Showing the first eight; more decompositions exist.
