Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515594, here are decompositions:

7 + 515587 = 515594
31 + 515563 = 515594
193 + 515401 = 515594
223 + 515371 = 515594
271 + 515323 = 515594
283 + 515311 = 515594
367 + 515227 = 515594
421 + 515173 = 515594

Showing the first eight; more decompositions exist.
