Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171772, here are decompositions:

11 + 171761 = 171772
53 + 171719 = 171772
59 + 171713 = 171772
101 + 171671 = 171772
113 + 171659 = 171772
131 + 171641 = 171772
233 + 171539 = 171772
281 + 171491 = 171772

Showing the first eight; more decompositions exist.
