Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521242, here are decompositions:

11 + 521231 = 521242
41 + 521201 = 521242
89 + 521153 = 521242
179 + 521063 = 521242
191 + 521051 = 521242
233 + 521009 = 521242
353 + 520889 = 521242
389 + 520853 = 521242

Showing the first eight; more decompositions exist.
