Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521354, here are decompositions:

37 + 521317 = 521354
73 + 521281 = 521354
103 + 521251 = 521354
181 + 521173 = 521354
193 + 521161 = 521354
307 + 521047 = 521354
313 + 521041 = 521354
331 + 521023 = 521354

Showing the first eight; more decompositions exist.
