Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521974, here are decompositions:

71 + 521903 = 521974
113 + 521861 = 521974
197 + 521777 = 521974
251 + 521723 = 521974
281 + 521693 = 521974
317 + 521657 = 521974
491 + 521483 = 521974
503 + 521471 = 521974

Showing the first eight; more decompositions exist.
