Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4278, here are decompositions:

5 + 4273 = 4278
7 + 4271 = 4278
17 + 4261 = 4278
19 + 4259 = 4278
37 + 4241 = 4278
47 + 4231 = 4278
59 + 4219 = 4278
61 + 4217 = 4278

Showing the first eight; more decompositions exist.
