Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177522, here are decompositions:

11 + 177511 = 177522
29 + 177493 = 177522
41 + 177481 = 177522
89 + 177433 = 177522
101 + 177421 = 177522
113 + 177409 = 177522
139 + 177383 = 177522
199 + 177323 = 177522

Showing the first eight; more decompositions exist.
