Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177898, here are decompositions:

5 + 177893 = 177898
11 + 177887 = 177898
59 + 177839 = 177898
101 + 177797 = 177898
107 + 177791 = 177898
137 + 177761 = 177898
251 + 177647 = 177898
359 + 177539 = 177898

Showing the first eight; more decompositions exist.
