Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27240, here are decompositions:

29 + 27211 = 27240
43 + 27197 = 27240
61 + 27179 = 27240
97 + 27143 = 27240
113 + 27127 = 27240
131 + 27109 = 27240
137 + 27103 = 27240
149 + 27091 = 27240

Showing the first eight; more decompositions exist.
