Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153918, here are decompositions:

5 + 153913 = 153918
7 + 153911 = 153918
29 + 153889 = 153918
31 + 153887 = 153918
41 + 153877 = 153918
47 + 153871 = 153918
101 + 153817 = 153918
179 + 153739 = 153918

Showing the first eight; more decompositions exist.
