Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11008, here are decompositions:

5 + 11003 = 11008
29 + 10979 = 11008
59 + 10949 = 11008
71 + 10937 = 11008
149 + 10859 = 11008
227 + 10781 = 11008
269 + 10739 = 11008
317 + 10691 = 11008

Showing the first eight; more decompositions exist.
