Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27180, here are decompositions:

37 + 27143 = 27180
53 + 27127 = 27180
71 + 27109 = 27180
73 + 27107 = 27180
89 + 27091 = 27180
103 + 27077 = 27180
107 + 27073 = 27180
113 + 27067 = 27180

Showing the first eight; more decompositions exist.
