Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521554, here are decompositions:

3 + 521551 = 521554
17 + 521537 = 521554
71 + 521483 = 521554
83 + 521471 = 521554
107 + 521447 = 521554
191 + 521363 = 521554
197 + 521357 = 521554
311 + 521243 = 521554

Showing the first eight; more decompositions exist.
