Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11090, here are decompositions:

3 + 11087 = 11090
7 + 11083 = 11090
19 + 11071 = 11090
31 + 11059 = 11090
43 + 11047 = 11090
97 + 10993 = 11090
103 + 10987 = 11090
151 + 10939 = 11090

Showing the first eight; more decompositions exist.
