Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522148, here are decompositions:

89 + 522059 = 522148
101 + 522047 = 522148
131 + 522017 = 522148
149 + 521999 = 522148
167 + 521981 = 522148
251 + 521897 = 522148
269 + 521879 = 522148
317 + 521831 = 522148

Showing the first eight; more decompositions exist.
