Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513902, here are decompositions:

3 + 513899 = 513902
31 + 513871 = 513902
61 + 513841 = 513902
73 + 513829 = 513902
163 + 513739 = 513902
211 + 513691 = 513902
223 + 513679 = 513902
229 + 513673 = 513902

Showing the first eight; more decompositions exist.
