Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505902, here are decompositions:

31 + 505871 = 505902
79 + 505823 = 505902
83 + 505819 = 505902
139 + 505763 = 505902
191 + 505711 = 505902
193 + 505709 = 505902
211 + 505691 = 505902
233 + 505669 = 505902

Showing the first eight; more decompositions exist.
