Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142896, here are decompositions:

23 + 142873 = 142896
29 + 142867 = 142896
59 + 142837 = 142896
97 + 142799 = 142896
107 + 142789 = 142896
109 + 142787 = 142896
137 + 142759 = 142896
139 + 142757 = 142896

Showing the first eight; more decompositions exist.
