Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164162, here are decompositions:

13 + 164149 = 164162
73 + 164089 = 164162
139 + 164023 = 164162
151 + 164011 = 164162
181 + 163981 = 164162
373 + 163789 = 164162
409 + 163753 = 164162
421 + 163741 = 164162

Showing the first eight; more decompositions exist.
