Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520890, here are decompositions:

23 + 520867 = 520890
37 + 520853 = 520890
53 + 520837 = 520890
103 + 520787 = 520890
127 + 520763 = 520890
131 + 520759 = 520890
173 + 520717 = 520890
191 + 520699 = 520890

Showing the first eight; more decompositions exist.
