Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 42550, here are decompositions:

17 + 42533 = 42550
41 + 42509 = 42550
59 + 42491 = 42550
83 + 42467 = 42550
89 + 42461 = 42550
107 + 42443 = 42550
113 + 42437 = 42550
191 + 42359 = 42550

Showing the first eight; more decompositions exist.
