Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515798, here are decompositions:

37 + 515761 = 515798
61 + 515737 = 515798
97 + 515701 = 515798
211 + 515587 = 515798
397 + 515401 = 515798
421 + 515377 = 515798
487 + 515311 = 515798
571 + 515227 = 515798

Showing the first eight; more decompositions exist.
