Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525940, here are decompositions:

3 + 525937 = 525940
17 + 525923 = 525940
47 + 525893 = 525940
53 + 525887 = 525940
71 + 525869 = 525940
101 + 525839 = 525940
131 + 525809 = 525940
167 + 525773 = 525940

Showing the first eight; more decompositions exist.
