Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515812, here are decompositions:

29 + 515783 = 515812
41 + 515771 = 515812
71 + 515741 = 515812
131 + 515681 = 515812
149 + 515663 = 515812
173 + 515639 = 515812
191 + 515621 = 515812
233 + 515579 = 515812

Showing the first eight; more decompositions exist.
