Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142902, here are decompositions:

5 + 142897 = 142902
29 + 142873 = 142902
31 + 142871 = 142902
61 + 142841 = 142902
103 + 142799 = 142902
113 + 142789 = 142902
131 + 142771 = 142902
191 + 142711 = 142902

Showing the first eight; more decompositions exist.
