Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 169782, here are decompositions:

5 + 169777 = 169782
13 + 169769 = 169782
29 + 169753 = 169782
31 + 169751 = 169782
73 + 169709 = 169782
89 + 169693 = 169782
101 + 169681 = 169782
149 + 169633 = 169782

Showing the first eight; more decompositions exist.
