Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177040, here are decompositions:

29 + 177011 = 177040
89 + 176951 = 177040
107 + 176933 = 177040
113 + 176927 = 177040
137 + 176903 = 177040
191 + 176849 = 177040
233 + 176807 = 177040
251 + 176789 = 177040

Showing the first eight; more decompositions exist.
