Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11158, here are decompositions:

41 + 11117 = 11158
71 + 11087 = 11158
89 + 11069 = 11158
101 + 11057 = 11158
131 + 11027 = 11158
179 + 10979 = 11158
269 + 10889 = 11158
311 + 10847 = 11158

Showing the first eight; more decompositions exist.
