Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11050, here are decompositions:

3 + 11047 = 11050
23 + 11027 = 11050
47 + 11003 = 11050
71 + 10979 = 11050
101 + 10949 = 11050
113 + 10937 = 11050
167 + 10883 = 11050
191 + 10859 = 11050

Showing the first eight; more decompositions exist.
