Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722292, here are decompositions:

193 + 8722099 = 8722292
199 + 8722093 = 8722292
211 + 8722081 = 8722292
283 + 8722009 = 8722292
379 + 8721913 = 8722292
409 + 8721883 = 8722292
619 + 8721673 = 8722292
661 + 8721631 = 8722292

Showing the first eight; more decompositions exist.
