Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738172, here are decompositions:

11 + 8738161 = 8738172
43 + 8738129 = 8738172
71 + 8738101 = 8738172
83 + 8738089 = 8738172
89 + 8738083 = 8738172
101 + 8738071 = 8738172
139 + 8738033 = 8738172
193 + 8737979 = 8738172

Showing the first eight; more decompositions exist.
