Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148902, here are decompositions:

11 + 148891 = 148902
29 + 148873 = 148902
41 + 148861 = 148902
43 + 148859 = 148902
73 + 148829 = 148902
109 + 148793 = 148902
139 + 148763 = 148902
179 + 148723 = 148902

Showing the first eight; more decompositions exist.
