Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545678, here are decompositions:

31 + 545647 = 545678
37 + 545641 = 545678
61 + 545617 = 545678
79 + 545599 = 545678
127 + 545551 = 545678
151 + 545527 = 545678
157 + 545521 = 545678
181 + 545497 = 545678

Showing the first eight; more decompositions exist.
