Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528974, here are decompositions:

3 + 528971 = 528974
7 + 528967 = 528974
97 + 528877 = 528974
151 + 528823 = 528974
163 + 528811 = 528974
211 + 528763 = 528974
283 + 528691 = 528974
307 + 528667 = 528974

Showing the first eight; more decompositions exist.
