Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515164, here are decompositions:

11 + 515153 = 515164
53 + 515111 = 515164
197 + 514967 = 515164
311 + 514853 = 515164
317 + 514847 = 515164
431 + 514733 = 515164
521 + 514643 = 515164
593 + 514571 = 515164

Showing the first eight; more decompositions exist.
