Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668892, here are decompositions:

3 + 8668889 = 8668892
19 + 8668873 = 8668892
61 + 8668831 = 8668892
79 + 8668813 = 8668892
109 + 8668783 = 8668892
151 + 8668741 = 8668892
181 + 8668711 = 8668892
283 + 8668609 = 8668892

Showing the first eight; more decompositions exist.
