Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142530, here are decompositions:

29 + 142501 = 142530
61 + 142469 = 142530
97 + 142433 = 142530
103 + 142427 = 142530
109 + 142421 = 142530
127 + 142403 = 142530
139 + 142391 = 142530
149 + 142381 = 142530

Showing the first eight; more decompositions exist.
