Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521498, here are decompositions:

7 + 521491 = 521498
97 + 521401 = 521498
139 + 521359 = 521498
181 + 521317 = 521498
199 + 521299 = 521498
331 + 521167 = 521498
337 + 521161 = 521498
379 + 521119 = 521498

Showing the first eight; more decompositions exist.
