Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529478, here are decompositions:

7 + 529471 = 529478
67 + 529411 = 529478
97 + 529381 = 529478
151 + 529327 = 529478
241 + 529237 = 529478
349 + 529129 = 529478
487 + 528991 = 529478
601 + 528877 = 529478

Showing the first eight; more decompositions exist.
