Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40156, here are decompositions:

3 + 40153 = 40156
5 + 40151 = 40156
29 + 40127 = 40156
167 + 39989 = 40156
173 + 39983 = 40156
227 + 39929 = 40156
269 + 39887 = 40156
293 + 39863 = 40156

Showing the first eight; more decompositions exist.
