Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478636, here are decompositions:

5 + 478631 = 478636
47 + 478589 = 478636
113 + 478523 = 478636
233 + 478403 = 478636
293 + 478343 = 478636
383 + 478253 = 478636
467 + 478169 = 478636
479 + 478157 = 478636

Showing the first eight; more decompositions exist.
