Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 525890, here are decompositions:

3 + 525887 = 525890
19 + 525871 = 525890
73 + 525817 = 525890
109 + 525781 = 525890
151 + 525739 = 525890
163 + 525727 = 525890
181 + 525709 = 525890
193 + 525697 = 525890

Showing the first eight; more decompositions exist.
