Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521692, here are decompositions:

23 + 521669 = 521692
89 + 521603 = 521692
173 + 521519 = 521692
263 + 521429 = 521692
293 + 521399 = 521692
383 + 521309 = 521692
449 + 521243 = 521692
461 + 521231 = 521692

Showing the first eight; more decompositions exist.
