Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171090, here are decompositions:

11 + 171079 = 171090
13 + 171077 = 171090
37 + 171053 = 171090
41 + 171049 = 171090
43 + 171047 = 171090
47 + 171043 = 171090
61 + 171029 = 171090
67 + 171023 = 171090

Showing the first eight; more decompositions exist.
