Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27138, here are decompositions:

11 + 27127 = 27138
29 + 27109 = 27138
31 + 27107 = 27138
47 + 27091 = 27138
61 + 27077 = 27138
71 + 27067 = 27138
79 + 27059 = 27138
107 + 27031 = 27138

Showing the first eight; more decompositions exist.
