Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10918, here are decompositions:

29 + 10889 = 10918
59 + 10859 = 10918
71 + 10847 = 10918
137 + 10781 = 10918
179 + 10739 = 10918
227 + 10691 = 10918
251 + 10667 = 10918
311 + 10607 = 10918

Showing the first eight; more decompositions exist.
