Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27278, here are decompositions:

7 + 27271 = 27278
19 + 27259 = 27278
37 + 27241 = 27278
67 + 27211 = 27278
151 + 27127 = 27278
211 + 27067 = 27278
331 + 26947 = 27278
397 + 26881 = 27278

Showing the first eight; more decompositions exist.
