Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10278, here are decompositions:

5 + 10273 = 10278
7 + 10271 = 10278
11 + 10267 = 10278
19 + 10259 = 10278
31 + 10247 = 10278
67 + 10211 = 10278
97 + 10181 = 10278
101 + 10177 = 10278

Showing the first eight; more decompositions exist.
