Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528704, here are decompositions:

13 + 528691 = 528704
31 + 528673 = 528704
37 + 528667 = 528704
73 + 528631 = 528704
193 + 528511 = 528704
271 + 528433 = 528704
313 + 528391 = 528704
331 + 528373 = 528704

Showing the first eight; more decompositions exist.
