Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146142, here are decompositions:

43 + 146099 = 146142
79 + 146063 = 146142
83 + 146059 = 146142
109 + 146033 = 146142
131 + 146011 = 146142
151 + 145991 = 146142
173 + 145969 = 146142
179 + 145963 = 146142

Showing the first eight; more decompositions exist.
