Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521150, here are decompositions:

13 + 521137 = 521150
31 + 521119 = 521150
43 + 521107 = 521150
103 + 521047 = 521150
109 + 521041 = 521150
127 + 521023 = 521150
181 + 520969 = 521150
193 + 520957 = 521150

Showing the first eight; more decompositions exist.
