Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515708, here are decompositions:

7 + 515701 = 515708
31 + 515677 = 515708
97 + 515611 = 515708
307 + 515401 = 515708
331 + 515377 = 515708
337 + 515371 = 515708
397 + 515311 = 515708
619 + 515089 = 515708

Showing the first eight; more decompositions exist.
