Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478244, here are decompositions:

3 + 478241 = 478244
31 + 478213 = 478244
37 + 478207 = 478244
73 + 478171 = 478244
157 + 478087 = 478244
181 + 478063 = 478244
271 + 477973 = 478244
331 + 477913 = 478244

Showing the first eight; more decompositions exist.
