Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521316, here are decompositions:

7 + 521309 = 521316
17 + 521299 = 521316
73 + 521243 = 521316
137 + 521179 = 521316
139 + 521177 = 521316
149 + 521167 = 521316
163 + 521153 = 521316
179 + 521137 = 521316

Showing the first eight; more decompositions exist.
