Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88540, here are decompositions:

17 + 88523 = 88540
41 + 88499 = 88540
47 + 88493 = 88540
71 + 88469 = 88540
113 + 88427 = 88540
239 + 88301 = 88540
251 + 88289 = 88540
281 + 88259 = 88540

Showing the first eight; more decompositions exist.
