Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523026, here are decompositions:

5 + 523021 = 523026
19 + 523007 = 523026
37 + 522989 = 523026
67 + 522959 = 523026
79 + 522947 = 523026
83 + 522943 = 523026
107 + 522919 = 523026
139 + 522887 = 523026

Showing the first eight; more decompositions exist.
