Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522242, here are decompositions:

3 + 522239 = 522242
13 + 522229 = 522242
31 + 522211 = 522242
43 + 522199 = 522242
163 + 522079 = 522242
181 + 522061 = 522242
313 + 521929 = 522242
373 + 521869 = 522242

Showing the first eight; more decompositions exist.
