Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154170, here are decompositions:

11 + 154159 = 154170
13 + 154157 = 154170
17 + 154153 = 154170
43 + 154127 = 154170
59 + 154111 = 154170
73 + 154097 = 154170
83 + 154087 = 154170
89 + 154081 = 154170

Showing the first eight; more decompositions exist.
