Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146172, here are decompositions:

11 + 146161 = 146172
31 + 146141 = 146172
73 + 146099 = 146172
79 + 146093 = 146172
109 + 146063 = 146172
113 + 146059 = 146172
139 + 146033 = 146172
149 + 146023 = 146172

Showing the first eight; more decompositions exist.
