Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142608, here are decompositions:

7 + 142601 = 142608
17 + 142591 = 142608
19 + 142589 = 142608
41 + 142567 = 142608
61 + 142547 = 142608
71 + 142537 = 142608
79 + 142529 = 142608
107 + 142501 = 142608

Showing the first eight; more decompositions exist.
