Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11218, here are decompositions:

5 + 11213 = 11218
41 + 11177 = 11218
47 + 11171 = 11218
59 + 11159 = 11218
101 + 11117 = 11218
131 + 11087 = 11218
149 + 11069 = 11218
191 + 11027 = 11218

Showing the first eight; more decompositions exist.
