Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521494, here are decompositions:

3 + 521491 = 521494
11 + 521483 = 521494
23 + 521471 = 521494
47 + 521447 = 521494
101 + 521393 = 521494
131 + 521363 = 521494
137 + 521357 = 521494
227 + 521267 = 521494

Showing the first eight; more decompositions exist.
