Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528950, here are decompositions:

3 + 528947 = 528950
67 + 528883 = 528950
73 + 528877 = 528950
127 + 528823 = 528950
139 + 528811 = 528950
151 + 528799 = 528950
241 + 528709 = 528950
271 + 528679 = 528950

Showing the first eight; more decompositions exist.
