Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500478, here are decompositions:

5 + 500473 = 500478
7 + 500471 = 500478
19 + 500459 = 500478
47 + 500431 = 500478
61 + 500417 = 500478
89 + 500389 = 500478
109 + 500369 = 500478
137 + 500341 = 500478

Showing the first eight; more decompositions exist.
