Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478026, here are decompositions:

53 + 477973 = 478026
79 + 477947 = 478026
113 + 477913 = 478026
127 + 477899 = 478026
163 + 477863 = 478026
179 + 477847 = 478026
229 + 477797 = 478026
257 + 477769 = 478026

Showing the first eight; more decompositions exist.
