Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 528090, here are decompositions:

37 + 528053 = 528090
47 + 528043 = 528090
89 + 528001 = 528090
97 + 527993 = 528090
103 + 527987 = 528090
107 + 527983 = 528090
109 + 527981 = 528090
149 + 527941 = 528090

Showing the first eight; more decompositions exist.
