Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11648, here are decompositions:

31 + 11617 = 11648
61 + 11587 = 11648
97 + 11551 = 11648
151 + 11497 = 11648
157 + 11491 = 11648
181 + 11467 = 11648
211 + 11437 = 11648
331 + 11317 = 11648

Showing the first eight; more decompositions exist.
