Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 522078, here are decompositions:

5 + 522073 = 522078
17 + 522061 = 522078
19 + 522059 = 522078
31 + 522047 = 522078
41 + 522037 = 522078
61 + 522017 = 522078
79 + 521999 = 522078
97 + 521981 = 522078

Showing the first eight; more decompositions exist.
