Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737818, here are decompositions:

17 + 8737801 = 8737818
29 + 8737789 = 8737818
101 + 8737717 = 8737818
109 + 8737709 = 8737818
149 + 8737669 = 8737818
151 + 8737667 = 8737818
191 + 8737627 = 8737818
227 + 8737591 = 8737818

Showing the first eight; more decompositions exist.
