Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618526, here are decompositions:

43 + 8618483 = 8618526
47 + 8618479 = 8618526
83 + 8618443 = 8618526
97 + 8618429 = 8618526
113 + 8618413 = 8618526
139 + 8618387 = 8618526
149 + 8618377 = 8618526
197 + 8618329 = 8618526

Showing the first eight; more decompositions exist.
