Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177556, here are decompositions:

3 + 177553 = 177556
17 + 177539 = 177556
23 + 177533 = 177556
83 + 177473 = 177556
89 + 177467 = 177556
173 + 177383 = 177556
233 + 177323 = 177556
317 + 177239 = 177556

Showing the first eight; more decompositions exist.
