Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521962, here are decompositions:

59 + 521903 = 521962
83 + 521879 = 521962
101 + 521861 = 521962
131 + 521831 = 521962
149 + 521813 = 521962
173 + 521789 = 521962
239 + 521723 = 521962
269 + 521693 = 521962

Showing the first eight; more decompositions exist.
