Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27940, here are decompositions:

23 + 27917 = 27940
47 + 27893 = 27940
89 + 27851 = 27940
113 + 27827 = 27940
131 + 27809 = 27940
137 + 27803 = 27940
149 + 27791 = 27940
167 + 27773 = 27940

Showing the first eight; more decompositions exist.
