Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522090, here are decompositions:

7 + 522083 = 522090
11 + 522079 = 522090
17 + 522073 = 522090
29 + 522061 = 522090
31 + 522059 = 522090
43 + 522047 = 522090
53 + 522037 = 522090
73 + 522017 = 522090

Showing the first eight; more decompositions exist.
