Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 505678, here are decompositions:

59 + 505619 = 505678
71 + 505607 = 505678
167 + 505511 = 505678
197 + 505481 = 505678
269 + 505409 = 505678
311 + 505367 = 505678
359 + 505319 = 505678
401 + 505277 = 505678

Showing the first eight; more decompositions exist.
