Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11088, here are decompositions:

5 + 11083 = 11088
17 + 11071 = 11088
19 + 11069 = 11088
29 + 11059 = 11088
31 + 11057 = 11088
41 + 11047 = 11088
61 + 11027 = 11088
101 + 10987 = 11088

Showing the first eight; more decompositions exist.
