Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521044, here are decompositions:

3 + 521041 = 521044
5 + 521039 = 521044
23 + 521021 = 521044
101 + 520943 = 521044
131 + 520913 = 521044
191 + 520853 = 521044
257 + 520787 = 521044
281 + 520763 = 521044

Showing the first eight; more decompositions exist.
