Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177658, here are decompositions:

11 + 177647 = 177658
191 + 177467 = 177658
227 + 177431 = 177658
311 + 177347 = 177658
389 + 177269 = 177658
401 + 177257 = 177658
419 + 177239 = 177658
449 + 177209 = 177658

Showing the first eight; more decompositions exist.
