Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 461728, here are decompositions:

11 + 461717 = 461728
41 + 461687 = 461728
89 + 461639 = 461728
101 + 461627 = 461728
167 + 461561 = 461728
317 + 461411 = 461728
347 + 461381 = 461728
401 + 461327 = 461728

Showing the first eight; more decompositions exist.
