Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515624, here are decompositions:

3 + 515621 = 515624
13 + 515611 = 515624
37 + 515587 = 515624
61 + 515563 = 515624
223 + 515401 = 515624
313 + 515311 = 515624
331 + 515293 = 515624
397 + 515227 = 515624

Showing the first eight; more decompositions exist.
