Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478184, here are decompositions:

13 + 478171 = 478184
73 + 478111 = 478184
97 + 478087 = 478184
193 + 477991 = 478184
211 + 477973 = 478184
271 + 477913 = 478184
337 + 477847 = 478184
373 + 477811 = 478184

Showing the first eight; more decompositions exist.
