Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722692, here are decompositions:

19 + 8722673 = 8722692
31 + 8722661 = 8722692
61 + 8722631 = 8722692
71 + 8722621 = 8722692
79 + 8722613 = 8722692
89 + 8722603 = 8722692
151 + 8722541 = 8722692
193 + 8722499 = 8722692

Showing the first eight; more decompositions exist.
