Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528764, here are decompositions:

73 + 528691 = 528764
97 + 528667 = 528764
277 + 528487 = 528764
331 + 528433 = 528764
373 + 528391 = 528764
541 + 528223 = 528764
547 + 528217 = 528764
601 + 528163 = 528764

Showing the first eight; more decompositions exist.
