Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525840, here are decompositions:

23 + 525817 = 525840
31 + 525809 = 525840
59 + 525781 = 525840
67 + 525773 = 525840
71 + 525769 = 525840
101 + 525739 = 525840
109 + 525731 = 525840
113 + 525727 = 525840

Showing the first eight; more decompositions exist.
