Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177858, here are decompositions:

17 + 177841 = 177858
19 + 177839 = 177858
47 + 177811 = 177858
61 + 177797 = 177858
67 + 177791 = 177858
71 + 177787 = 177858
97 + 177761 = 177858
167 + 177691 = 177858

Showing the first eight; more decompositions exist.
