Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522156, here are decompositions:

29 + 522127 = 522156
43 + 522113 = 522156
73 + 522083 = 522156
83 + 522073 = 522156
97 + 522059 = 522156
109 + 522047 = 522156
139 + 522017 = 522156
157 + 521999 = 522156

Showing the first eight; more decompositions exist.
