Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42544, here are decompositions:

11 + 42533 = 42544
53 + 42491 = 42544
71 + 42473 = 42544
83 + 42461 = 42544
101 + 42443 = 42544
107 + 42437 = 42544
137 + 42407 = 42544
251 + 42293 = 42544

Showing the first eight; more decompositions exist.
