Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738180, here are decompositions:

19 + 8738161 = 8738180
79 + 8738101 = 8738180
97 + 8738083 = 8738180
109 + 8738071 = 8738180
127 + 8738053 = 8738180
307 + 8737873 = 8738180
313 + 8737867 = 8738180
331 + 8737849 = 8738180

Showing the first eight; more decompositions exist.
