Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73156, here are decompositions:

23 + 73133 = 73156
29 + 73127 = 73156
113 + 73043 = 73156
137 + 73019 = 73156
179 + 72977 = 73156
197 + 72959 = 73156
233 + 72923 = 73156
263 + 72893 = 73156

Showing the first eight; more decompositions exist.
