Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738160, here are decompositions:

31 + 8738129 = 8738160
37 + 8738123 = 8738160
59 + 8738101 = 8738160
71 + 8738089 = 8738160
73 + 8738087 = 8738160
89 + 8738071 = 8738160
107 + 8738053 = 8738160
113 + 8738047 = 8738160

Showing the first eight; more decompositions exist.
