Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478922, here are decompositions:

43 + 478879 = 478922
61 + 478861 = 478922
79 + 478843 = 478922
109 + 478813 = 478922
181 + 478741 = 478922
193 + 478729 = 478922
211 + 478711 = 478922
271 + 478651 = 478922

Showing the first eight; more decompositions exist.
