Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521992, here are decompositions:

11 + 521981 = 521992
89 + 521903 = 521992
113 + 521879 = 521992
131 + 521861 = 521992
173 + 521819 = 521992
179 + 521813 = 521992
239 + 521753 = 521992
269 + 521723 = 521992

Showing the first eight; more decompositions exist.
