Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525680, here are decompositions:

3 + 525677 = 525680
31 + 525649 = 525680
73 + 525607 = 525680
97 + 525583 = 525680
109 + 525571 = 525680
139 + 525541 = 525680
151 + 525529 = 525680
163 + 525517 = 525680

Showing the first eight; more decompositions exist.
