Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505860, here are decompositions:

37 + 505823 = 505860
41 + 505819 = 505860
79 + 505781 = 505860
83 + 505777 = 505860
97 + 505763 = 505860
101 + 505759 = 505860
149 + 505711 = 505860
151 + 505709 = 505860

Showing the first eight; more decompositions exist.
