Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 73170, here are decompositions:

29 + 73141 = 73170
37 + 73133 = 73170
43 + 73127 = 73170
79 + 73091 = 73170
107 + 73063 = 73170
109 + 73061 = 73170
127 + 73043 = 73170
131 + 73039 = 73170

Showing the first eight; more decompositions exist.
