Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525860, here are decompositions:

43 + 525817 = 525860
79 + 525781 = 525860
151 + 525709 = 525860
163 + 525697 = 525860
211 + 525649 = 525860
277 + 525583 = 525860
331 + 525529 = 525860
367 + 525493 = 525860

Showing the first eight; more decompositions exist.
