Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523072, here are decompositions:

23 + 523049 = 523072
41 + 523031 = 523072
83 + 522989 = 523072
113 + 522959 = 523072
191 + 522881 = 523072
233 + 522839 = 523072
311 + 522761 = 523072
353 + 522719 = 523072

Showing the first eight; more decompositions exist.
