Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737806, here are decompositions:

5 + 8737801 = 8737806
17 + 8737789 = 8737806
23 + 8737783 = 8737806
43 + 8737763 = 8737806
89 + 8737717 = 8737806
97 + 8737709 = 8737806
107 + 8737699 = 8737806
109 + 8737697 = 8737806

Showing the first eight; more decompositions exist.
