Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142962, here are decompositions:

13 + 142949 = 142962
23 + 142939 = 142962
59 + 142903 = 142962
89 + 142873 = 142962
151 + 142811 = 142962
163 + 142799 = 142962
173 + 142789 = 142962
191 + 142771 = 142962

Showing the first eight; more decompositions exist.
