Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478402, here are decompositions:

3 + 478399 = 478402
11 + 478391 = 478402
59 + 478343 = 478402
131 + 478271 = 478402
149 + 478253 = 478402
233 + 478169 = 478402
263 + 478139 = 478402
401 + 478001 = 478402

Showing the first eight; more decompositions exist.
