Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 478746, here are decompositions:

5 + 478741 = 478746
7 + 478739 = 478746
17 + 478729 = 478746
19 + 478727 = 478746
67 + 478679 = 478746
109 + 478637 = 478746
157 + 478589 = 478746
167 + 478579 = 478746

Showing the first eight; more decompositions exist.
