Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 22278, here are decompositions:

5 + 22273 = 22278
7 + 22271 = 22278
19 + 22259 = 22278
31 + 22247 = 22278
89 + 22189 = 22278
107 + 22171 = 22278
131 + 22147 = 22278
149 + 22129 = 22278

Showing the first eight; more decompositions exist.
