Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545784, here are decompositions:

11 + 545773 = 545784
37 + 545747 = 545784
53 + 545731 = 545784
61 + 545723 = 545784
73 + 545711 = 545784
137 + 545647 = 545784
163 + 545621 = 545784
167 + 545617 = 545784

Showing the first eight; more decompositions exist.
