Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505742, here are decompositions:

31 + 505711 = 505742
73 + 505669 = 505742
79 + 505663 = 505742
103 + 505639 = 505742
109 + 505633 = 505742
229 + 505513 = 505742
241 + 505501 = 505742
283 + 505459 = 505742

Showing the first eight; more decompositions exist.
