Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27946, here are decompositions:

3 + 27943 = 27946
5 + 27941 = 27946
29 + 27917 = 27946
53 + 27893 = 27946
137 + 27809 = 27946
167 + 27779 = 27946
173 + 27773 = 27946
179 + 27767 = 27946

Showing the first eight; more decompositions exist.
