Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 526878, here are decompositions:

7 + 526871 = 526878
19 + 526859 = 526878
41 + 526837 = 526878
47 + 526831 = 526878
97 + 526781 = 526878
101 + 526777 = 526878
137 + 526741 = 526878
139 + 526739 = 526878

Showing the first eight; more decompositions exist.
