Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515992, here are decompositions:

23 + 515969 = 515992
41 + 515951 = 515992
131 + 515861 = 515992
149 + 515843 = 515992
179 + 515813 = 515992
251 + 515741 = 515992
311 + 515681 = 515992
353 + 515639 = 515992

Showing the first eight; more decompositions exist.
