Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 177772, here are decompositions:

11 + 177761 = 177772
29 + 177743 = 177772
149 + 177623 = 177772
233 + 177539 = 177772
239 + 177533 = 177772
389 + 177383 = 177772
449 + 177323 = 177772
503 + 177269 = 177772

Showing the first eight; more decompositions exist.
