Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 515902, here are decompositions:

29 + 515873 = 515902
41 + 515861 = 515902
59 + 515843 = 515902
89 + 515813 = 515902
131 + 515771 = 515902
239 + 515663 = 515902
251 + 515651 = 515902
263 + 515639 = 515902

Showing the first eight; more decompositions exist.
