Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27018, here are decompositions:

7 + 27011 = 27018
31 + 26987 = 27018
37 + 26981 = 27018
59 + 26959 = 27018
67 + 26951 = 27018
71 + 26947 = 27018
97 + 26921 = 27018
127 + 26891 = 27018

Showing the first eight; more decompositions exist.
