Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521674, here are decompositions:

3 + 521671 = 521674
5 + 521669 = 521674
17 + 521657 = 521674
71 + 521603 = 521674
107 + 521567 = 521674
137 + 521537 = 521674
191 + 521483 = 521674
227 + 521447 = 521674

Showing the first eight; more decompositions exist.
