Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521602, here are decompositions:

83 + 521519 = 521602
131 + 521471 = 521602
173 + 521429 = 521602
233 + 521369 = 521602
239 + 521363 = 521602
293 + 521309 = 521602
359 + 521243 = 521602
401 + 521201 = 521602

Showing the first eight; more decompositions exist.
