Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505538, here are decompositions:

37 + 505501 = 505538
79 + 505459 = 505538
109 + 505429 = 505538
127 + 505411 = 505538
139 + 505399 = 505538
181 + 505357 = 505538
199 + 505339 = 505538
211 + 505327 = 505538

Showing the first eight; more decompositions exist.
