Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104156, here are decompositions:

7 + 104149 = 104156
37 + 104119 = 104156
43 + 104113 = 104156
67 + 104089 = 104156
97 + 104059 = 104156
103 + 104053 = 104156
109 + 104047 = 104156
163 + 103993 = 104156

Showing the first eight; more decompositions exist.
