Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505958, here are decompositions:

31 + 505927 = 505958
139 + 505819 = 505958
181 + 505777 = 505958
199 + 505759 = 505958
421 + 505537 = 505958
457 + 505501 = 505958
499 + 505459 = 505958
547 + 505411 = 505958

Showing the first eight; more decompositions exist.
