Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172090, here are decompositions:

11 + 172079 = 172090
41 + 172049 = 172090
59 + 172031 = 172090
89 + 172001 = 172090
167 + 171923 = 172090
173 + 171917 = 172090
227 + 171863 = 172090
239 + 171851 = 172090

Showing the first eight; more decompositions exist.
