Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171792, here are decompositions:

29 + 171763 = 171792
31 + 171761 = 171792
59 + 171733 = 171792
73 + 171719 = 171792
79 + 171713 = 171792
113 + 171679 = 171792
139 + 171653 = 171792
151 + 171641 = 171792

Showing the first eight; more decompositions exist.
