Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478248, here are decompositions:

5 + 478243 = 478248
7 + 478241 = 478248
41 + 478207 = 478248
59 + 478189 = 478248
79 + 478169 = 478248
109 + 478139 = 478248
137 + 478111 = 478248
149 + 478099 = 478248

Showing the first eight; more decompositions exist.
