Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177992, here are decompositions:

13 + 177979 = 177992
43 + 177949 = 177992
79 + 177913 = 177992
103 + 177889 = 177992
109 + 177883 = 177992
151 + 177841 = 177992
181 + 177811 = 177992
229 + 177763 = 177992

Showing the first eight; more decompositions exist.
