Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 486478, here are decompositions:

29 + 486449 = 486478
71 + 486407 = 486478
89 + 486389 = 486478
101 + 486377 = 486478
137 + 486341 = 486478
149 + 486329 = 486478
197 + 486281 = 486478
257 + 486221 = 486478

Showing the first eight; more decompositions exist.
