Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525986, here are decompositions:

3 + 525983 = 525986
7 + 525979 = 525986
37 + 525949 = 525986
73 + 525913 = 525986
277 + 525709 = 525986
337 + 525649 = 525986
379 + 525607 = 525986
457 + 525529 = 525986

Showing the first eight; more decompositions exist.
