Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528908, here are decompositions:

31 + 528877 = 528908
97 + 528811 = 528908
109 + 528799 = 528908
199 + 528709 = 528908
229 + 528679 = 528908
241 + 528667 = 528908
277 + 528631 = 528908
349 + 528559 = 528908

Showing the first eight; more decompositions exist.
