Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 545826, here are decompositions:

37 + 545789 = 545826
53 + 545773 = 545826
67 + 545759 = 545826
79 + 545747 = 545826
103 + 545723 = 545826
163 + 545663 = 545826
179 + 545647 = 545826
227 + 545599 = 545826

Showing the first eight; more decompositions exist.
