Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505600, here are decompositions:

41 + 505559 = 505600
89 + 505511 = 505600
107 + 505493 = 505600
131 + 505469 = 505600
191 + 505409 = 505600
233 + 505367 = 505600
281 + 505319 = 505600
317 + 505283 = 505600

Showing the first eight; more decompositions exist.
