Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148878, here are decompositions:

5 + 148873 = 148878
11 + 148867 = 148878
17 + 148861 = 148878
19 + 148859 = 148878
61 + 148817 = 148878
97 + 148781 = 148878
131 + 148747 = 148878
151 + 148727 = 148878

Showing the first eight; more decompositions exist.
