Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 11440, here are decompositions:

3 + 11437 = 11440
17 + 11423 = 11440
29 + 11411 = 11440
41 + 11399 = 11440
47 + 11393 = 11440
71 + 11369 = 11440
89 + 11351 = 11440
167 + 11273 = 11440

Showing the first eight; more decompositions exist.
