Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11638, here are decompositions:

5 + 11633 = 11638
17 + 11621 = 11638
41 + 11597 = 11638
59 + 11579 = 11638
89 + 11549 = 11638
149 + 11489 = 11638
167 + 11471 = 11638
191 + 11447 = 11638

Showing the first eight; more decompositions exist.
