Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525866, here are decompositions:

97 + 525769 = 525866
127 + 525739 = 525866
139 + 525727 = 525866
157 + 525709 = 525866
283 + 525583 = 525866
337 + 525529 = 525866
349 + 525517 = 525866
373 + 525493 = 525866

Showing the first eight; more decompositions exist.
