Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522142, here are decompositions:

29 + 522113 = 522142
59 + 522083 = 522142
83 + 522059 = 522142
149 + 521993 = 522142
239 + 521903 = 522142
263 + 521879 = 522142
281 + 521861 = 522142
311 + 521831 = 522142

Showing the first eight; more decompositions exist.
