Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722328, here are decompositions:

31 + 8722297 = 8722328
37 + 8722291 = 8722328
157 + 8722171 = 8722328
211 + 8722117 = 8722328
229 + 8722099 = 8722328
331 + 8721997 = 8722328
421 + 8721907 = 8722328
661 + 8721667 = 8722328

Showing the first eight; more decompositions exist.
