Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505588, here are decompositions:

29 + 505559 = 505588
107 + 505481 = 505588
179 + 505409 = 505588
269 + 505319 = 505588
311 + 505277 = 505588
401 + 505187 = 505588
431 + 505157 = 505588
449 + 505139 = 505588

Showing the first eight; more decompositions exist.
