Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164156, here are decompositions:

7 + 164149 = 164156
43 + 164113 = 164156
67 + 164089 = 164156
163 + 163993 = 164156
229 + 163927 = 164156
337 + 163819 = 164156
367 + 163789 = 164156
523 + 163633 = 164156

Showing the first eight; more decompositions exist.
