Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521042, here are decompositions:

3 + 521039 = 521042
19 + 521023 = 521042
61 + 520981 = 521042
73 + 520969 = 521042
79 + 520963 = 521042
229 + 520813 = 521042
283 + 520759 = 521042
409 + 520633 = 521042

Showing the first eight; more decompositions exist.
