Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142152, here are decompositions:

29 + 142123 = 142152
41 + 142111 = 142152
53 + 142099 = 142152
103 + 142049 = 142152
113 + 142039 = 142152
181 + 141971 = 142152
191 + 141961 = 142152
193 + 141959 = 142152

Showing the first eight; more decompositions exist.
