Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738190, here are decompositions:

29 + 8738161 = 8738190
61 + 8738129 = 8738190
67 + 8738123 = 8738190
89 + 8738101 = 8738190
101 + 8738089 = 8738190
103 + 8738087 = 8738190
107 + 8738083 = 8738190
137 + 8738053 = 8738190

Showing the first eight; more decompositions exist.
