Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27128, here are decompositions:

19 + 27109 = 27128
37 + 27091 = 27128
61 + 27067 = 27128
67 + 27061 = 27128
97 + 27031 = 27128
181 + 26947 = 27128
307 + 26821 = 27128
397 + 26731 = 27128

Showing the first eight; more decompositions exist.
