Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478750, here are decompositions:

3 + 478747 = 478750
11 + 478739 = 478750
23 + 478727 = 478750
53 + 478697 = 478750
71 + 478679 = 478750
113 + 478637 = 478750
179 + 478571 = 478750
227 + 478523 = 478750

Showing the first eight; more decompositions exist.
