Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521394, here are decompositions:

17 + 521377 = 521394
31 + 521363 = 521394
37 + 521357 = 521394
113 + 521281 = 521394
127 + 521267 = 521394
151 + 521243 = 521394
163 + 521231 = 521394
193 + 521201 = 521394

Showing the first eight; more decompositions exist.
