Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27918, here are decompositions:

17 + 27901 = 27918
67 + 27851 = 27918
71 + 27847 = 27918
101 + 27817 = 27918
109 + 27809 = 27918
127 + 27791 = 27918
139 + 27779 = 27918
151 + 27767 = 27918

Showing the first eight; more decompositions exist.
