Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177980, here are decompositions:

13 + 177967 = 177980
31 + 177949 = 177980
37 + 177943 = 177980
67 + 177913 = 177980
73 + 177907 = 177980
97 + 177883 = 177980
139 + 177841 = 177980
157 + 177823 = 177980

Showing the first eight; more decompositions exist.
