Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522842, here are decompositions:

3 + 522839 = 522842
13 + 522829 = 522842
31 + 522811 = 522842
79 + 522763 = 522842
139 + 522703 = 522842
163 + 522679 = 522842
181 + 522661 = 522842
241 + 522601 = 522842

Showing the first eight; more decompositions exist.
