Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27956, here are decompositions:

3 + 27953 = 27956
13 + 27943 = 27956
37 + 27919 = 27956
73 + 27883 = 27956
109 + 27847 = 27956
139 + 27817 = 27956
157 + 27799 = 27956
163 + 27793 = 27956

Showing the first eight; more decompositions exist.
