Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 164312, here are decompositions:

3 + 164309 = 164312
13 + 164299 = 164312
61 + 164251 = 164312
73 + 164239 = 164312
79 + 164233 = 164312
103 + 164209 = 164312
139 + 164173 = 164312
163 + 164149 = 164312

Showing the first eight; more decompositions exist.
