Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668744, here are decompositions:

3 + 8668741 = 8668744
5 + 8668739 = 8668744
23 + 8668721 = 8668744
47 + 8668697 = 8668744
101 + 8668643 = 8668744
107 + 8668637 = 8668744
131 + 8668613 = 8668744
167 + 8668577 = 8668744

Showing the first eight; more decompositions exist.
