Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668898, here are decompositions:

61 + 8668837 = 8668898
67 + 8668831 = 8668898
97 + 8668801 = 8668898
157 + 8668741 = 8668898
211 + 8668687 = 8668898
349 + 8668549 = 8668898
379 + 8668519 = 8668898
397 + 8668501 = 8668898

Showing the first eight; more decompositions exist.
