Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521274, here are decompositions:

7 + 521267 = 521274
23 + 521251 = 521274
31 + 521243 = 521274
43 + 521231 = 521274
73 + 521201 = 521274
97 + 521177 = 521274
101 + 521173 = 521274
107 + 521167 = 521274

Showing the first eight; more decompositions exist.
