Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177512, here are decompositions:

19 + 177493 = 177512
31 + 177481 = 177512
79 + 177433 = 177512
103 + 177409 = 177512
193 + 177319 = 177512
211 + 177301 = 177512
229 + 177283 = 177512
421 + 177091 = 177512

Showing the first eight; more decompositions exist.
