Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526890, here are decompositions:

19 + 526871 = 526890
31 + 526859 = 526890
37 + 526853 = 526890
53 + 526837 = 526890
59 + 526831 = 526890
61 + 526829 = 526890
109 + 526781 = 526890
113 + 526777 = 526890

Showing the first eight; more decompositions exist.
