Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668838, here are decompositions:

7 + 8668831 = 8668838
37 + 8668801 = 8668838
97 + 8668741 = 8668838
127 + 8668711 = 8668838
151 + 8668687 = 8668838
229 + 8668609 = 8668838
337 + 8668501 = 8668838
349 + 8668489 = 8668838

Showing the first eight; more decompositions exist.
