Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148872, here are decompositions:

5 + 148867 = 148872
11 + 148861 = 148872
13 + 148859 = 148872
19 + 148853 = 148872
43 + 148829 = 148872
79 + 148793 = 148872
89 + 148783 = 148872
109 + 148763 = 148872

Showing the first eight; more decompositions exist.
