Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525830, here are decompositions:

13 + 525817 = 525830
61 + 525769 = 525830
103 + 525727 = 525830
181 + 525649 = 525830
223 + 525607 = 525830
313 + 525517 = 525830
337 + 525493 = 525830
373 + 525457 = 525830

Showing the first eight; more decompositions exist.
