Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142908, here are decompositions:

5 + 142903 = 142908
11 + 142897 = 142908
37 + 142871 = 142908
41 + 142867 = 142908
67 + 142841 = 142908
71 + 142837 = 142908
97 + 142811 = 142908
109 + 142799 = 142908

Showing the first eight; more decompositions exist.
