Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529778, here are decompositions:

31 + 529747 = 529778
37 + 529741 = 529778
97 + 529681 = 529778
199 + 529579 = 529778
307 + 529471 = 529778
367 + 529411 = 529778
397 + 529381 = 529778
421 + 529357 = 529778

Showing the first eight; more decompositions exist.
