Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177918, here are decompositions:

5 + 177913 = 177918
11 + 177907 = 177918
29 + 177889 = 177918
31 + 177887 = 177918
79 + 177839 = 177918
107 + 177811 = 177918
127 + 177791 = 177918
131 + 177787 = 177918

Showing the first eight; more decompositions exist.
