Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520842, here are decompositions:

5 + 520837 = 520842
29 + 520813 = 520842
79 + 520763 = 520842
83 + 520759 = 520842
139 + 520703 = 520842
151 + 520691 = 520842
163 + 520679 = 520842
193 + 520649 = 520842

Showing the first eight; more decompositions exist.
