Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142932, here are decompositions:

29 + 142903 = 142932
59 + 142873 = 142932
61 + 142871 = 142932
173 + 142759 = 142932
199 + 142733 = 142932
233 + 142699 = 142932
313 + 142619 = 142932
331 + 142601 = 142932

Showing the first eight; more decompositions exist.
