Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505942, here are decompositions:

23 + 505919 = 505942
71 + 505871 = 505942
131 + 505811 = 505942
179 + 505763 = 505942
233 + 505709 = 505942
251 + 505691 = 505942
383 + 505559 = 505942
419 + 505523 = 505942

Showing the first eight; more decompositions exist.
