Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27390, here are decompositions:

23 + 27367 = 27390
29 + 27361 = 27390
53 + 27337 = 27390
61 + 27329 = 27390
107 + 27283 = 27390
109 + 27281 = 27390
113 + 27277 = 27390
131 + 27259 = 27390

Showing the first eight; more decompositions exist.
